It also includes a reference beam unit for transmitting a reference beam in a reference beam transmission direction with respect to the main axis of the housing.
    Description and advantages of the invention
    The present invention relates to a laser measuring device of the type defined above characterized in that the main beam unit and the reference beam unit emit on different sides of the housing.
    There is thus a laser measuring device having a particularly important functionality. The measurement function according to the laser rule is used in combination with the marking function. The invention avoids the use of other means for measuring length; it allows a particularly efficient work. In particular, it is possible to arrive at a very large distance between the emission range of the main beam and the emission range of the reference beam. The invention achieves a high level of accuracy for marking the length. The laser measuring device makes it possible to project in a particularly practical manner using the reference beam and the main beam, a predefined length, in particular a desired length and / or predefined by an operator (user) on an object, especially a room. In particular, the laser measuring device independently determines at least the emission direction of the main beam. In particular, a given length is predefined and the laser measuring device is positioned relative to a measuring object, for example on a workbench. The laser measuring device notably sends a main beam and a reference beam on the surface of the measuring object, which makes it possible to project two reference points on the surface and determines the distance in the beam emission direction. main and in the direction of the reference beam. In particular, the laser measuring device determines the angle of the transmission direction for which the distance of the marking points corresponds to the desired distance and it represents the direction of emission in the form of an angle.
    Preferably, the laser measuring device adjusts the emission direction of the main beam to avoid any difference between the distance of the marking points and the desired length. Preferably, the main beam unit transmits a main beam and the reference beam unit emits a reference beam; the main beam and the reference beam are at least transversely oriented relative to one another in the different housing sides. The term "box side" in this context refers in particular to the plane at the lateral surfaces delimiting the side. Preferably, the casing has a shape that is at least substantially parallelepipedal. Preferably, the housing portions have rectangular sides in the plane that delimits the square. The main axis of the housing in connection with the present description is at least substantially parallel to an axis passing through one side of the housing in the main extension direction of the housing. Preferably, the different sides of the housing are at least substantially oriented transversely relative to each other. Preferably, a first side of the housing is at least substantially perpendicular to the main axis of the housing and another side of the housing is at least substantially parallel to the main axis of the housing.
    In particular, the main beam unit is for example provided to emit by a side of the housing which is at least substantially perpendicular to the main axis of the housing.
    In particular, the reference beam unit emits for example by a side of the housing which is at least substantially parallel to the main axis of the housing. The expression "emit from different sides of the housing" according to the present invention means that the emission is done with a main beam unit which emits a main beam at least substantially in the transverse direction to the first side of the housing and a unit a reference beam which emits a reference beam at least substantially transversely to another side of the housing, the first side of the housing and the other side of the housing being oriented relative to each other at least substantially transversely and or the main beam unit and the reference beam unit are provided on different sides of the housing to emit the main beam and the reference beam.
    A substantially parallel orientation according to the present invention designates the orientation of a direction relative to the reference direction, in particular a plane, and this direction makes, with respect to the reference direction, a gap notably less than 8 ° and advantageously less than 5 ° and particularly advantageously less than 2 °. A substantially transverse orientation means according to the present invention that the orientation is that of a direction with respect to a reference direction and / or a reference plane and this direction is at least different from a direction substantially parallel to the direction of rotation. reference and / or the reference plane and in particular inclined or perpendicular to the reference direction and / or to the reference axis. The expression that a direction is substantially perpendicular means according to the present invention that the orientation of the direction is defined with respect to the reference direction and this direction is the reference direction in particular considered in a plane make a 90 ° angle and this angle has a maximum deviation which is in particular less than 8 ° and advantageously less than 5 ° and in a particularly advantageous manner, the angle is less than 2 °.
    Preferably, the main beam unit and the reference beam unit each comprise optical transmission means and optical transmission means of the main beam unit and the unit transmission means. reference beam are on different sides of the housing.
    An emission means according to the present invention is a means for driving and / or deflecting a laser beam at its output from the housing and / or its passage in the environment of the laser measuring device. The transmission means is for example a lens, a prism or a mirror. It is also conceivable that the reference beam unit and the main beam unit are on the same side of the housing and that the reference beam unit and / or the main beam unit for transmission are provided on another side of the case, different from the previous one.
    Preferably, the reference number is in the form of a continuous and / or quasi-continuous laser beam, preferably in the visible frequency range. Preferably, the main beam is a continuous or quasi-continuous laser beam, preferably in the visible frequency range.
    As a variant, the main beam and / or the reference beam work with a frequency in the visible range. A quasi-continuous laser beam according to the present invention is for example a pulsed laser beam with a beam deflection means and the pulse interval is less than 0.5 s, preferably less than 0.1 s and in particular less than 0 , 05 s and particularly preferably less than 0.02 s.
    Preferably, the main beam unit comprises at least one laser source that generates the main beam. Alternatively, the main beam unit also has other laser sources for generating other beams at least independent of the main beam. Preferably, the laser measuring device is in the form of a portable laser measuring device having a mass of less than 500 g and preferably less than 400 g and particularly preferably less than 300 g. The laser measuring device comprises at least one gripping surface.
    According to the present description, the expression "intended for" means that it is a specially programmed means, designed and / or equipped to perform certain functions. The fact that an object is provided to perform a certain function means in particular that the object performs or provides this determined function in at least one application and / or operating state.
    Advantageously, the direction of the reference beam is variable independently of the direction of emission of the main beam, which makes it possible to arrive at a minimum distance between the laser measuring device and the measurement object. In a limited space, it will be possible to reach the important measuring range for the laser measuring device. This allows a very comfortable use. The term "independent" associated with variable means in this context that the direction of the reference beam can be changed for a constant transmission direction of the main beam. Preferably, the emission direction of the main beam and the reference transmission direction can vary independently of one another. In particular, the direction of emission of at least one main beam and the direction of the reference beam relative to the axis of the housing have no fixed angular relationship connecting them. It can be envisaged that the direction of the reference beam is variable according to the discrete angular steps, for example angular steps of 30 °. In at least one operating state, the direction of the reference beam forms with the main axis of the housing an angle of 90 °. An alternative embodiment can be envisaged in which the direction of the reference beam is at an angle of 90 ° with respect to the main axis of the housing and that only the direction of emission of the main beam is variable. Alternatively, the direction of the reference beam can be varied continuously. Preferably, the laser measuring device has a maximum value for the angle between the emission direction of at least one main beam and the reference beam which is at least equal to 120 ° and preferably at least equal to 150 ° and in a particularly preferred manner, equal to 180 ° and exceptionally equal to at least 210 °.
    According to another feature, the reference beam unit has an emission angle range with an axis of symmetry that is at least substantially transverse, especially at least substantially perpendicular to the main axis of the housing. This makes it possible to have a particularly advantageous angle between at least one main beam and the reference beam. Unfavorable marking and / or measurement angles are avoided. The range of the emission angle in this context refers in particular to the totality of the emission angles of a beam. The axis of symmetry in the present context designates the bisector of the angular emission range. Preferably, the main beam unit has an emission angle range that is at least substantially parallel to the axis of symmetry which is the main axis of the housing. Preferably, the axis of symmetry of the range of the emission angle of the reference beam unit and the axis of symmetry of the range of the emission angle of the main beam unit are at least practically perpendicular to each other.
    According to an advantageous development, the laser measuring device has a reference beam sensor unit for capturing at least one reflection of the reference beam to determine the distance. Preferably, the reference beam sensor unit captures at least one reflection of the reference beam to determine the distance in the direction of the reference beam. Preferably, the reference beam sensor unit captures at least one reflection of the reference beam to determine the distance between a marking point generated using the reference beam and a marking point and a marking point. generated by the main beam. The capture of a reflection means in the present context that a portion of the laser beam returned by the distant object is captured by the laser measuring device, this light being diffracted and / or reflected by the distant object. There is thus a laser measurement device of particularly flexible use. Preferably, the laser meter has a main beam sensor unit for capturing at least one reflection of at least one main beam for determining a distance. Preferably, the main beam sensor unit captures at least one reflection of the main beam to determine the distance in the emission direction of the main beam.
    Preferably, the main beam sensor unit captures at least one reflection of the main beam to determine the distance between the marking point generated using the reference beam and the marking point generated with the main beam. The reference beam sensor unit is preferably a laser beam sensor unit. The main beam sensor unit is preferably a laser beam sensor unit. A laser beam sensor unit in the present context is a unit for detecting at least one measuring beam. Preferably, the laser beam sensor unit comprises at least one detection element which, in at least one operating state, provides a detection signal dependent on the incident light intensity. The detector element is for example a radiation-sensitive element, in particular a photosensitive radiation such as a photodiode, for example a PIN diode or an avalanche photodiode.
    According to an advantageous development, the laser measuring device has at least one control and / or regulation unit for at least a distance measurement using the main beam and / or the reference beam, controlled and / or regulated the desired length of a projection. This makes it possible to have a laser measurement device that is particularly easy to use. The control and / or regulation unit is in particular a unit comprising at least one control electronics. The control electronics is a unit comprising a processor and a memory and an operating program stored in the memory. Projection within the meaning of the present invention means that an image is formed remotely, in particular by means of a beam generator unit. The control and / or regulation unit is preferably connected by a signal transmission link to at least one laser beam sensor unit of the laser measuring device, in particular to the reference beam sensor unit and / or to the main beam sensor unit.
    Preferably, the control and / or regulation unit uses the phase of the reflected light component by comparing it with the phase of the emitted laser beam and / or the time of travel of the light of the emitted laser beam. the distant object which at least partially reflects the laser beam and back to the laser measuring device. Preferably, the control and / or regulation unit operates at least substantially at the same time the distances in two directions independent of one another for a measurement. This quasi-simultaneity according to the present invention means that the operations are carried out in a time interval which differs at most from 0.5 s and preferably at most 0.2 s and in a particularly preferential manner from 0.1 s and in particular 0.01 s. Preferably, the control and / or regulation unit controls the projection of the desired length using the main beam and / or using the reference beam. Preferably, the control and / or regulation unit makes it possible to modify the direction of emission of the main beam and / or of the direction of the reference beam, at least as a function of the measurement of the distance using the main beam and / or reference beam. Preferably, the control and / or regulation unit adjusts the angle between the direction of the reference beam and the direction of emission of the main beam and in particular according to a position and / or an orientation of the housing with respect to the measurement object and / or ensures servocontrol. Preferably, the laser measuring device comprises at least one angle-sensing means exchanging signals with the control and / or regulation unit and entering the angle between the direction of the reference beam and the direction of the beam. emission of the main beam. It can be envisaged that the angle capture means detects the angle between the direction of the reference beam and the main axis of the housing and / or the angle between the emission direction of the main beam and the main axis of the housing. housing and / or the angle between the direction of emission of the main beam and the direction of the reference beam. In at least one operating state, the angle capture unit captures at least one angle between the direction of the reference beam and the direction of emission of the main beam to transmit it to the control unit and / or control for the reaction and / or as a basis for calculating a setpoint value of the angle.
    According to another characteristic, the control and / or regulation unit transmits to the observer a level of precision of the projected length marking. This makes it possible to achieve a particularly reliable length marking. Precision in this context is in particular a measure of the error, especially taking into account tolerances and / or geometrical data. A range of confidence can be considered as a level of precision.
    In addition, the object of the invention is to mark a desired length with the aid of a laser measuring device according to the invention, in which the main beam unit emits the main beam and the unit reference beam emits the reference beam for projecting a length marking on different sides of the housing, in particular on a distant object. This allows for a length marking in a small pass. A laser measuring device can be used in a large utilization range. The length marking according to the present invention is a marking having a first marking point generated by the reference beam and at least one other marking point generated by the main beam. Preferably, the length marking in an operating state corresponds to a length predefined by the observer which corresponds to the distance between the first marking point and at least one other marking point on the distant object. It can be envisaged that the reference beam and / or the main beam generate a marking sign different from a point, for example a linear shape, a T-shape or a similar shape. The main beam unit and the reference beam unit are in particular provided to mark a predefined length by emitting this length in at least two directions. Preferably, the main beam unit transmits in at least one transmission direction and the reference beam unit transmits in a direction different from the transmission direction. It is also possible to generate a marking in a particularly large length range.
    According to an advantageous development, in at least one step of the method, the direction of the reference beam is fixed with respect to the axis of the housing, which avoids unfavorable measurement provisions. Particularly advantageous measurement results will be obtained. One can consider manually adjusting the direction of the reference beam. It can also be envisaged that the control and / or regulation unit adjusts the direction of the reference beam semi-automatically or automatically. In the present context, the "automatic" setting means that the control and / or regulation unit fixes the direction of the reference beam at least practically autonomously, in particular according to predefined criteria, for example using a input unit and / or using a detection method, in particular according to the contour of a measurement object. The semiautomatic adjustment according to the present invention means that at least in part of the method, the direction of the reference beam can be modified by the observer, for example roughly oriented and that in at least one other part of the process, the The control and / or control unit changes the reference transmission direction, for example, an adjustment is then made.
    According to another characteristic, in at least one step of the method, a control and / or regulation unit of the laser measuring device controls and / or regulates the projection of the desired length at least as a function of the distance measurement using main beam and / or reference beam. This allows the observer to postpone a distance in a particularly simple manner. This avoids the adjustment of a reference panel or a stop as is the case for current distance measuring devices. The desired length according to the present invention is a set value given by the observer, for example introduced using a maneuvering unit and / or input or a measurement value recorded during an operation. measurement in the control and / or control unit. Preferably, the control and / or regulation unit calculates the distance between the reference beam and the main beam and projects the marking points from the distance data and / or angle data and / or function of the orientation of the main axis of the housing relative to the surface of the measuring object. Preferably, the control and / or regulation unit calculates and / or determines a setpoint angle in the emission direction at least for the main beam and which corresponds to the angle at which the main beam will be emitted for project the desired length. It can be envisaged that the control and / or regulation unit calculates the setpoint angle in the transmission direction directly by iteration. Preferably, the control and / or regulation unit starts a regulation operation for which the projected marking points are set to a predefined target value which corresponds to the desired length.
    Advantageously, in at least one step of the method, a control and / or regulation unit of the laser measuring device determines a level of precision of the length marking, which makes it possible to recognize the unfavorable measurement arrangements. This simplifies the processes. Preferably, the control and / or regulation unit calculates the pressure level at least as a function of distance measurement using the main beam and / or the reference beam and / or depending on the distance. angle between the main axis of the housing, the direction of the reference beam, the direction of emission of at least one main beam and / or the surface of the measuring object.
    According to another characteristic, in at least one step of the method, a control unit and / or regulator of the laser measuring device modified with the aid of the main beam unit, the direction of emission of at least the main beam to provide a level of accuracy. This allows the intuitive presentation of the level of precision. It can be envisaged that, with the main beam unit, the control and / or regulation unit periodically modifies the transmission direction, thus making it possible to display a set of marking points for the transmission of the level of precision and / or or using a set of main beams a set of marking points is projected to emit the level of precision. It is also conceivable that with the aid of the main beam and / or all the main beams, a line or other figure is projected to display the level of precision. Preferably, at least one extension of the line or another figure corresponds to the level of precision.
    According to an advantageous development, the position recognition unit of the laser measuring device detects the rest position of the housing and the control and / or control unit of the laser measuring device activates a marking mode as a function of the rest position. This automates the work process; The position recognition unit according to the present invention is a unit which makes it possible to grasp the variations of movement and / or a rotation of the housing of the laser measuring device. Preferably, the position recognition unit comprises at least one intertiel sensor, a compass, and / or a receiving element for receiving a signal, in particular a radio signal, from a positioning system. Preferably, the position capture unit makes it possible to grasp the position of the housing, in particular with respect to the gravitational field and / or a reference system for orientation and / or leveling of the housing. The marking mode according to the invention is in particular an operating mode in which the laser measuring device emits to mark a predefined length, a reference beam and at least one main beam and adjusts the distance between the marking point generated by the reference beam and the marking point generated by the main beam.
    According to another characteristic, the subject of the invention is a control and / or regulation unit of the laser measuring device which determines the angle between the main axis of the housing and the surface of a measuring object for projecting the length marking. This allows a very accurate measurement of a partially inaccessible path. Preferably, the operator orients the main axis of the housing according to the angle measurement with respect to the surface of the measuring object and / or the surface of an auxiliary object, for example at least practically parallel or perpendicular to the surface. It can also be envisaged that the control and / or regulation unit modifies the emission control of at least the main beam and / or the reference beam as a function of the angular measurement.

The sides 28, 30 of the housing constituting the top and the bottom are opposite to each other. The sides 28, 30 of the housing constituting the top and bottom are at least substantially parallel to the main axis 14 of the housing. The sides 32 and 34 of the housing constituting the first end face and the other end face are opposite one another. The sides of the housing 32, 34 constituting the first end face and the other end face are at least substantially perpendicular to the main axis 14 of the housing. The housing sides 36, 38 formed as the first longitudinal side and as another longitudinal side are spaced from each other. The housing sides 36, 38 formed as a first longitudinal side and as another longitudinal side are at least substantially parallel to the main axis 14 of the housing. The housing 12 has a main extension direction which is at least substantially parallel to the four sides 28, 30, 36, 38 of the housing. In the present embodiment, the main axis 14 of the housing is parallel to the main extension direction. Alternatively, the housing 12 may also have a different shape, for example a rod shape or a handle shape. The main transmitting unit and the reference transmitting unit transmit on different sides 32, 36 of the housing 12. The main transmitting unit and the reference transmitting unit, related to the the section which is central to the housing direction and is perpendicular to the main axis 14 of the housing, is on different sides. The main transmitting unit of this embodiment emits the main beam 16 on the side 32 of the housing which constitutes the first front face. The main transmitting unit transmits the main beam 16 at least substantially transversely to the side 32 of the housing which constitutes the first front face. The reference transmission unit of this exemplary embodiment emits the reference beam 24 through the side 36 of the housing which constitutes the first longitudinal side.

In the present embodiment, the side 28 of the housing which constitutes the top (upper side), the side of the housing 36 which constitutes the first longitudinal face and the side 32 of the housing which forms the first end face form an orthogonal system. The main transmitting unit and the reference transmitting unit of this exemplary embodiment are associated with different sides 32, 36 of the housing. The housing 12 has a transmission window 54 for the output of the main beam 16 of the housing 12. The first end face of the housing 12 has a wall. The transmission window 54 is a transparent zone of the side wall 32 of the housing forming the first end face. The housing 12 has another emission window 56. The first longitudinal side of the housing 12 has a wall. The other emission window 56 is a transparent zone of the wall of the side 36 of the housing 12 constituting the first longitudinal face. The transmission windows 54, 56 of the present embodiment are spaced apart from each other. The maximum distance between the emission windows 54, 56 is preferably less than 160 mm, and in particular less than 120 mm and particularly preferably it is less than 80 mm. In particular, the distance between the transmission windows 54, 56 is at least half of the extension of the housing 12 in the main direction of the extension. It is also possible to envisage for the emission windows 54, 56 a larger or smaller distance.
    Alternatively, it is also conceivable that the main transmission unit and the auxiliary transmission unit are on the same side (same face) of the housing 28, 30, 32, 34, 36, 38 for example on the face 28 of the housing constituting the top. In a similar manner to the present exemplary embodiment, in such an example, the main transmission unit emits a side 32 of the housing constituting the first end face and the auxiliary transmitting unit emits from the side 36 of the housing which constitutes the first longitudinal face.

In particular, the reference transmission unit has a beam guiding means, such as for example a prism and / or a mirror for directing and / or deflecting the reference beam to be emitted by the side 36 of the housing constituting the first longitudinal face.

The maneuvering and input unit 58 allows the operator to enter commands to perform measurements using the main transmitting unit and / or the transmitting reference unit. The main transmission unit has a non-detailed laser source continuously generating a laser beam. The main transmission unit has a non-detailed beam deflection means for modifying the transmission direction 18, 20, 22 of the main beam 16. The transmission direction 18, 20, 22 of the main beam 16 of the present The embodiment may be modified at least continuously in a range of emission angle 66. The deflection means changes the angle 60, 62 between the transmission direction 18, 20, 22 and the main axis 14 of the housing to adjust this angle. The beam deflection means adjusts the transmission direction 18, 20, 22 at least substantially parallel to the direction of the main axis 14 of the housing. But it can be envisaged that the beam deflection means deviates the laser beam from the laser source periodically in two or more different transmission directions 18, 20, 22; thus all the images of the perceived beam are enlarged practically continuously and which are deployed in a set of different transmission directions 18, 20, 22. Preferably, the beam deflection means periodically deflects the laser beam supplied by the laser source between two different transmission directions 18, 22, in particular by sweeping between the two transmission directions 18, 22 to generate / project a line perceptible continuously.
    The transmission reference direction 26 can be varied independently of the transmission direction 18, 20, 22 of the main beam 16. The transmission reference unit has a laser source providing a continuous laser beam. The transmission reference unit has a non-detailed beam deflection means for modifying the transmission reference direction 26. The beam deflection means is used to modify and adjust the angle 64 between the reference direction beam 26 and the main axis 14 of the housing. The maneuvering and input unit 58 comprises an operating element for entering a desired value for the emission reference direction 26. According to an alternative embodiment, the transmission reference direction 26, for example, is manually adjusted. using a screening linked to a beam deflection means preferably for example at an angle 64 of 30 °, 60 °, 90 °, 120 ° or 150 ° relative to the main axis 14 of the housing.
    It is also possible to block the transmission reference direction 26 at an angle 64 relative to the main axis 14 of the housing, for example, at an angle 64 at least substantially equal to 90 °.

The control and / or control unit 44 uses the signal from the main beam sensor unit to determine a distance. The control and / or control unit 44 uses the signal from the beam sensor reference unit to determine a distance. The control and / or regulation unit 44 regulates the transmission direction 18, 20, 22 of the main beam 16 as a function of the beam reference direction 26, as a function of the path traveled by the reference beam 24 it meets the measuring object 48 as well as the path traveled by the main beam 16 to reach the measuring object 48. The control and / or control unit 44 generates a marking of projected length using the main beam 16 and the reference beam 24. The length marking consists of marking points 50, 52. The control and / or regulation unit 44 regulates the transmission device 18, 20, 22 of the main beam 16 as a function of the distance measurement in the direction of the reference beam 26 and as a function of the distance measurement in the transmission direction 18, 20, 22 of the main beam 16. The distance in the direction of the beam reference water 26 and the distance in the emission direction 18, 20, 22 of the main beam 16 depend on a measuring device, in particular the distance between the laser measuring device 10 and the measurement object 48 and / or the direction of the laser measuring device 10 with respect to the measuring object 48. The control and / or regulating unit 44 controls and / or controls the transmission direction 18, 20, 22 of the main beam 16 by means of the main transmission unit according to the orientation of the main axis 14 of the housing relative to the surface of the measuring object 48 on which is projected the mark of length for the desired length 46.

The control and / or regulation unit 44 calculates the accuracy of the projected length marking as a function of the direction of the reference beam 26, as a function of the path traveled by the reference beam 24 until it meets the target. measuring object 48, as a function of the transmission direction 18, 20, 22 of the main beam 16 as a function of the path traveled by the main beam 16 until it encounters the measuring object 48 and in function the orientation of the main axis 14 of the housing relative to the surface of the measuring object 48. The laser measuring device 10 comprises a transmission unit with a display 76 to give the level of accuracy of the marking length. In a variant, the transmission unit comprises an optical signaling element, for example an LED diode, an acoustic signaling element, a tactile signaling element and / or a vibration signaling element for emitting a signal, for example if the accuracy of the length marking falls below a threshold or if the accuracy of the length marking exceeds the threshold.
    According to a method step, optionally, the operator measures the distance using the laser measuring device 10 (see FIG. 3). In a first direct measurement mode, the laser measuring device 10 emits the main beam 16 in the emission direction 20. The transmission direction 20 is substantially parallel to the main axis 14 of the housing. The control and / or regulation unit 44 uses the travel time of the main beam 16 and / or the comparison of the phase of the main beam 16 and the phase of the reflection of the main beam 16 to determine the distance between the measurement 78, where the main beam 16 meets the measuring object 48 and the laser measuring device 10. The control and / or regulation unit 44 provides a measurement value which corresponds to the distance of the distance on the display 76 for the operator. The control and / or regulation unit 44 stores the measured value under the control of the operator in a memory element of the control and / or control unit 44.
    Alternatively, in a second indirect measurement mode, the laser measuring device 10 transmits the main beam 16 by alternating rapidly between a first transmission direction 18 and in another transmission direction 22, for example using a pivoting mirror or other technically interesting beam deflection means (see FIG. 4). It can also be envisaged that the indirect measurement mode has at least one detection function by which the control and / or regulation unit 44 makes it possible to recognize an abrupt variation in the measurement of the distance in the transmission direction 18. 22 of the main beam 16, which makes it possible to determine the contour position such as corners, grooves, steps and / or edges of a measuring object 48 and to correspondingly steer the direction of emission Alternatively, it can also be envisaged that the laser measuring device 10 emits a first main beam 16 in the transmission direction 18 and another main beam 16 in the emission direction 22. The Maneuver and input 58 comprises for example an operating element for adjusting the first transmission direction 18 and another transmission direction 22. The operator sets the first transmission direction 18 and is thus oriented on a first measurement point 80. The operator sets the other transmission direction 22 and thus moves to another measurement point 82. The control and / or regulation unit 44 determines the distance from the first transmission direction 18 and in the other transmission direction 22. The control and / or regulation unit 44 calculates the distance between the first measurement point 80 and the other measuring point 82 from the distance and the angle 60 between the first detection direction 18 and the main axis 14 of the housing as well as the angle 62 between the main axis 14 of the housing and another direction of emission 22. L The control and / or regulation unit 44 stores a measurement value, being controlled by the operator, in a first memory element of the control and / or regulation unit 44.
    The laser measuring device 10 has a position recognition unit for capturing movement and / or rotation of the housing 12 of the laser measuring device 10. In the operating mode of the laser measuring device 10, for example when the Laser measuring device 10 is placed on a support, such as the surface of a workbench 84 (see FIG. 5). The position recognition unit detects the rest position of the housing 12 of the laser measuring device 10 and activates a marking mode of the laser measuring device 10 according to this rest position. The position recognition unit recognizes in the present embodiment, a rest position because the laser measuring device 10 remains stationary for a selected time, for example equal to 5 s. Alternatively, the duration may be shorter or longer, it may be for example equal to 10 s, or 2 s or 1 s. In a variant, the marking mode of the laser measuring device 10 is activated with the maneuvering and input unit 58. In the marking mode, the control and / or regulation unit 44 regulates and / or controls in particular the transmission reference unit and / or the main transmission unit for projecting the length marking. In the marking device described, the emission plane of the laser measuring device 10 is substantially parallel to the surface of the workbench 84.
    According to a method of marking a length 46 with the aid of the laser measuring device 10, the user / operator predefines the desired length 46 as a target value for the length to be marked 46. For example, one selects / determines the set value from a measured value recorded during a previous measurement operation (see Figures 4 and 5). The measurement value is for example called in a memory element of the control and / or regulation unit 44. In a variant, the setpoint value is introduced by means of the maneuvering and input unit 58 .
    According to a method step, the beam reference direction 26 is fixed with respect to the main direction 14 of the housing. In this embodiment the angle 64 between the beam reference direction 26 and the casing main axis 14 is set according to the operator's set point to a value in a range of 30 °, 60 °, 90 °, 120 ° or 150 °. For example, the angle 64 is set to a value at least substantially equal to 90 °. With the aid of the maneuvering and input unit 58, the desired angular value is entered. It is also possible to manually adjust the reference transmission direction 26, for example by turning a mirror-shaped beam deflector means. It is also conceivable according to an exemplary embodiment, to set in a fixed way the reference transmission direction 26 relative to the main axis 14 of the housing, for example at least substantially perpendicular to the main axis 14 of the housing. The housing 12 is rotated, in particular about an axis perpendicular to the emission plane so that the reference beam 24 is oriented on a first marking point 50, for example an edge, an end, other desired point, at an end of the length 46 to project. Alternatively, with the aid of the operating and input unit 58, a search mode of the laser measuring device 10 is activated. The control and / or regulation unit 44 operates a search mode at the same time. the reference beam unit and the reference beam sensor unit, a sharp change in the distance measurement in the direction of the reference beam 26 and determines the position of the edge or the beam. end of the measuring object 48. The control and / or regulating unit 44 directs the reference beam 24 by means of a beam deflection means of the reference beam unit on the edge or on the end of the measuring object 48 where the abrupt variation of the measure of the distance occurs.
    According to another step of the method, the main beam unit emits the main beam 16 and the beam reference unit emits the reference beam 24 by different sides 32, 36 of the housing. The reference unit of the beam generates the first marking point 50 on the measurement object 48. The main beam unit generates the other marking point 52 on the measurement object 48. The main beam unit sends the main beam 16 to the first side 32 of the housing constituting the first end face and the reference beam unit sends the reference beam 24 by the side 36 of the housing which constitutes the first longitudinal face. The main beam unit and the reference beam unit emit in different directions. The reference beam sensor unit captures the reflection of the reference beam 24 by the measuring object 48. The reference beam sensor unit transmits a signal to the control and / or control unit 44. With the aid of the signal from the reference beam sensor unit 24, and from the travel time and / or the phase comparison between the transmitted reference beam 24 and the reflection, the control unit and or control 44 determines the distance traveled by the reference beam 24 to meet the measurement object 48. The control unit and / or control 44 sets the direction of transmission 20 of the main beam 16 to the using the main beam unit at the edge of the range of the emission angle of the main beam 66 facing the direction of the reference beam 26. The actual distance between the markings 50, 52 has a minimum value. The main beam sensor unit captures the refit of the main beam 16 on the object 48. The main beam sensor unit transmits the signal thus obtained to the control and / or regulation unit 44. The unit control and / or regulation 44 determines using the signal from the travel time and / or the phase comparison between the main beam 16 emitted and reflection, the distance traveled by the main beam 16 until the control and / or regulation unit 44 calculates the actual distance between the marking points 50, 52. The path between the marking points 50, 52, the path traversed by the reference beam 24, the path between the starting point of the reference beam 24 and the starting point of the main beam 16 and the path traveled by the main beam 16 constitute a square. The angle input means of the laser measuring device 10 is connected to the control and / or control unit 44 in signal transmission technique. The angular gripping means captures the angle 64 between the direction of the reference beam 26 and the main axis 14 of the housing to transmit this value of the angle 64 to the control and / or control unit 44. The means angular gripping grips the angle 60 between the main axis 14 of the housing and the direction of emission 20 of the main beam 16 to transmit the value of the angle 60 to the control unit and / or control 44. L control and / or regulating unit 44 determines, according to trigonometric calculation rules, from the angle between the direction of the reference beam 26 and the emission direction 20 of the main beam 16 as well as from the distance traveled by the reference beam 24, the distance between the starting point of the reference beam 24 and the starting point of the main beam 16 and the distance traveled by the main beam 16, the actual distance between marking points 50, 52.
    If the actual distance is greater than the setpoint, the sending unit provides an operator readable error message. The main axis 14 of the housing will be reoriented and / or a new reference beam direction 26 will be adjusted, for example using the search mode of the laser measuring device 10 manually. If the actual distance is less than the set point, the control and / or control unit 44 switches the main beam 16 to the main transmitting unit so that the actual distance between the marking points 50, 52 increases. The control and / or regulation unit 44 continuously calculates the distance between the marking points 50, 52 from the angle between the direction of the reference beam 26 and the emission direction 20 of the main beam 16, from the distance between the laser measuring device 10 and the object to be measured 48 in the direction of the reference beam 26 and from the distance between the laser measuring device 10 and the measured object 48 in the transmission direction 20 of the main beam 16. In the feedback loop, the direction of emission 20 of the main beam 16 is changed and the actual distance resulting from the marking points 50, 52 is determined. To approximate the actual distance marking points 50, 52 with respect to the setpoint, the transmission direction 20 is changed again, which results in a new passage in the feedback loop. The control and / or regulation unit 44 terminates the pivoting movement of the main beam 16 as soon as the actual distance calculated between the marking points 50, 52 is at least substantially equal to the set value. The control and / or regulation unit 44 iteratively calculates the transmission direction 20.
    The projected length marking is used, for example to definitively mark the measuring object 48 and display the desired length 46 and / or shorten the measuring object 48 to the desired length 46. Alternatively, may consider that the control and / or regulating unit 44 determines the angle 60 for the projection of the desired length 46 by means of the reference beam 24 and the main beam 16 starting from the largest angle between the direction of the reference beam 26 and the direction of radiation 20 of the main beam 16. According to another variant, the control and / or regulation unit 44 makes it possible to directly calculate the angle 60 of the transmission direction 20 of the main beam 16 from the support values, angle for which the distance between the marking points 50, 52 corresponds to the set value. According to a variant of the method, the direction of emission 20 of the main beam 16 is set to the angle 60 obtained by which the main beam 16 must be emitted in order to project the desired length 46. The feedback loop can be removed by iteration. According to an optional step, in order to control and / or improve the accuracy, it is possible in particular to measure the distance in the direction of the main beam 16 and then to adjust the angle 60 of the emission direction 20 of the main beam 16.
    FIG. 5 shows a first device for projecting the length marking to mark the desired length 46. In this device, the distance between the laser measuring device 10 and the measurement object 48 is for example substantially equal to half of measuring the length 46 to mark. By adjusting the distance of the marking points 50, 52 over the desired length 46, the transmission direction 20 of the device is substantially parallel to the main axis 14 of the housing.
    FIG. 6 shows another example of a projection arrangement for marking the desired length 46. In this device, the distance between the laser measuring device 10 and the measurement object 48 is smaller than that of the preceding arrangement. By moving the laser measuring device 10 in the present position, from the position described above, the actual distance of the marking points 50, 52 decreases at the same angle between the direction of the reference beam 26 and the direction of emission 20 of the main beam 16. The distance between the laser measuring device 10 and the measuring object 48 of the present arrangement corresponds for example to about a quarter of the measurement of the length 46 to be marked. The angle 64 between the direction of the reference beam 26 and the main axis 14 of the housing is as in the previous arrangement, set at least substantially 90 °. In a similar manner to the device described above, the angle acquisition means transmits the set angle value 64 of the direction of the reference beam 26 to the control and / or control unit 44. Depending on the At angle 64 of the direction of the reference beam 26, the control and / or regulation unit 44 calculates the angle 60 between the main axis 14 of the housing and the direction of emission 20 of the main beam 16. The unit control and / or regulation 44 determines the angle 60 between the main axis 14 of the housing and the direction of emission 20 of the main beam 16 and thus adjusts the direction of transmission 20 so that the actual distance between the points of marking 50, 52 correspond to the set point of the desired length 46. The angle 60 between the emission direction 20 of the main beam 16 and the main axis 14 of the housing has for the projection of the desired length 46 in this available sition, a value that is at least almost 30 degrees. The workbench 84 of this arrangement in comparison with the preceding arrangement has a larger free range, that is to say a free range of the emission device of the laser measuring device 10.
    Figure 7 shows another example of an arrangement for projecting the marking of the desired length 46. In this arrangement, the distance between the laser measuring device 10 and the measurement object 48 is further shortened by comparison with the preceding arrangements of FIGS. 5 and 6. By moving the laser measuring device 10 to a position corresponding to the described above to a position of the present arrangement, the actual distance of the marking points 50, 52 is reduced. The distance between the laser measuring device 10 and the measuring object 48 is, by way of example, substantially equal to one eighth of the measure of the length 46 to mark. The angle 64 between the direction of the reference beam 26 and the main axis 14 of the housing is substantially equal to 120 ° unlike the preceding arrangements. The angle sensing means transmits the angle 64 between the direction of the reference beam 26 and the main axis 14 of the housing. The control and / or regulation unit 44 regulates the transmission direction 20 so that the distance between the marking points 50, 52 corresponds to the setpoint value, that is to say to the desired length 46 . The angle 60 between the emission direction 20 of the main beam 16 and the main axis 14 of the housing in this arrangement, to project the desired length 46, has a value which is at least substantially equal to 30 °. The free range on the workbench 84 is even larger.
    According to another optional step of the method, the control and / or regulation unit 44 determines a level of accuracy of the length marking (see FIG. 8). The control and / or regulation unit 44 calculates the distance between the laser measuring device 10 and the measurement object 48 from the distance traveled by the reference beam 24 to the measurement object 48. , the distance traveled by the main beam 16 relative to the object 48 and the angle between the direction of the reference beam 26 and the transmission direction 18 of the main beam 16. The control unit and / or in the process step, from the calculated distance between the laser measuring device 10 and the measuring object 48, the control angle 44 determines the angle 64 between the direction of the reference beam 26 and the axis 14 of the housing and from the angle 60 between the emission direction 20 of the main beam 16, a level of accuracy of the length marking generated by the main beam 16 and the reference beam 24. The control unit and / or regulation ion 44 transmits the level of accuracy to the transmitting unit which indicates the level of accuracy to the operator on the display 76. Alternatively or additionally, the control and / or control unit 44 changes the direction transmission 20 of the main beam 16 to project the level of accuracy on the measurement object 48. The control and / or regulation unit 44 modifies the transmission direction 20, for example between the transmission direction 18 which marks the upper edge of a confidence range and a transmission direction 22 which marks the lower edge of a confidence range using the main beam unit. The control and / or regulation unit 44 controls and / or regulates the projection of two other marking points 86, 88 whose difference corresponds to the level of precision. It can be envisaged that the transmission direction 20 varies continuously, in particular periodically, between the two other marking points 86, 88 by scanning, which makes it possible to read the level of precision of the length marking in the form of a line on FIG. measuring object 48, line whose length corresponds to the level of precision.
    In a measurement method for measuring a path 90 which is not directly accessible, for example along the measuring object 48, the operator directs his laser measuring device 10 with respect to the direction of the path 90 to measure. Figure 9 shows a measurement arrangement according to which the measuring object 48 is a wall of a building. The measurement object 48 is only partially accessible. The path 90 to be measured is covered for example by an obstacle 92 such as a cabinet. The measuring object 48 may also be another object that is only partially accessible such as a ceiling, a floor, a vehicle or a rock wall. The control and / or regulating unit 44 determines the angle 94 of the main axis 14 of the housing relative to the surface of an auxiliary object 96 which forms with the measuring object 48 a known angle 98, by example an angle of 90 °. In the described measuring arrangement, the auxiliary object 96 is in the form of another construction wall. The control and / or regulation unit 44 transmits with the main beam unit, at short intervals, the main beam 16 in the transmission direction 20, parallel to the main axis 14 of the housing and in two other transmission directions 18, 22 which overlap the main axis 14 and form with it each time an acute angle. The other transmission directions 18, 22 according to the present embodiment make opposite angles (of the same value) with the main axis 14 of the housing. The control and / or control unit 44 determines, by means of the main beam sensor unit, the length of the paths traveled by the main beam 16 to the surface of the auxiliary object 96. control and / or control unit 44 based on the distance measurements in the transmission directions 18, 20, 22, an angle between the laser measuring device 10 and the auxiliary object 96. The control unit and / or regulation 44 determines the angle 94 of the main axis 14 of the housing of the laser measuring device 10 with the surface of the auxiliary object 96. The control and / or regulation unit 44 transmits the value angle 94 to the transmission unit which visibly displays the value to the operator. The operator rotates the laser measuring device 10 preferably about an axis perpendicular to the emission plane of the laser measuring device 10 so that the main axis 14 of the housing is perpendicular to the auxiliary object 96 ( see Figure 10). It can also be envisaged that the transmitting unit indicates the value of the angle 94 by a haptic, acoustic and / or optical signal, especially when arriving at a right angle. The reference beam unit transmits the reference beam 24 and the user positions the laser meter 10 so that the reference beam 24 indicates the end point of the path to be measured 90. The control unit and / or regulation 44 determines with the aid of the main beam sensor unit, the distance to the auxiliary object 96 which corresponds to the length of the path 90 to be measured. The transmitting unit indicates the distance using the display 76.
