    Externally visible orientation indication procedure and device for an optical sensor
    Background
    With a growing emphasis on the development of smart urban infrastructures, more emphasis will be placed on devices that may allow greater efficiencies, such as outdoor sensor devices. Sensing devices that can detect the flow and position of traffic and / or pedestrians have the potential to increase energy efficiency, since the detection and elimination of traffic jams, for example, can help reduce the use of transport fuels. Numerous other advantages are possible in the development of intelligent urban infrastructure. There remains a need for implementation and deployment of sensor devices that are easy to maintain in the field.
    During the installation of optical sensors (such as cameras) in external lighting devices, the sensors can be located inside an external housing to reliably and robustly facilitate the handling, cosmetic and environmental aspects. Doing this, however, makes adjusting the precise orientation of the sensors difficult once the system that includes the housing and the sensor is installed.
    For example, because a camera may be sealed inside the housing to protect and / or hide the camera, correct or change the camera's orientation (where the orientation can define the camera's field of vision) it may take time and considerable effort as it may be necessary to open the housing repeatedly to adjust and potentially readjust the orientation of the camera. Orienting the cameras during the start-up of camera systems can take up to an hour per manual work system, which represents a significant cost. This period of time is due to having to partially open and disassemble the housing after the system is installed in a device.

    Detailed description
    The object of the invention described herein provides an apparatus and method for adjusting orientations of optical sensors mounted on a device (such as cameras) with both an environmentally sealed adjustment as well as a visual indicator indicating the orientations of the sensors. The sensor can be arranged inside a housing to protect the sensor from environmental conditions, handling, vandalism,


    theft, etc., but may be mobile with respect to and within the housing to change the orientation (eg, field of view of the sensor) from outside the housing and provide a visual indication that represents the orientation of the sensor and that it is visible from outside the housing. In one example, this visual indication may be visible to an average human being without the help of one or more devices (for example, without the help of augmentation devices, X-ray systems, etc.).
    Figure 1 illustrates a sensor system 100 in accordance with an embodiment of the object of the invention. The sensor system 100 may be a luminaire that is mounted on another object (for example, a pole, wall, etc.). The sensor system 100 includes an outer shell 102, which may comprise a thermoplastic material. The housing 102 has a lower side 110 and an opposite upper side 112. One or more light emitting devices 104 are arranged in or connected to the housing 102. The light emitting devices 104 may include light emitting diodes (LEDs) or other light sources, reflectors and lenses, etc. The housing 102 includes one or more windows 106 that provide visibility inside the housing 102 from outside the housing 102 and that provide visibility outside the housing 102 from within the housing 102. The windows 106 may be made of glass, Plexiglas ™, or other light transmitting material that is transparent or transmitter at a wavelength of interest. The housing 102 can be sealed to prevent the entry of moisture, dirt or other environmental conditions inside the housing 102. The light emitting devices 104 and the windows 106 are arranged on or near the lower side 110 of the housing 102.
    One or more optical sensors 108 are disposed within the housing 102. The optical sensors 108 may represent cameras that obtain optical data, such as images and
    or videos The sensors 108 may be disposed within the housing 102 and located within the housing 102 such that a field of view of the sensors 108 includes space outside the housing 102. The field of view of a sensor 108 may include the area that it is captured or represented in the optical data generated by the sensor 108. The sensors 108 may be located inside the housing 102 so that the sensors 108 are not accessible from the outside of the housing 102. For example, the sensors 108 cannot touching or otherwise achieved without opening the housing 102, breaking the housing 102, or otherwise interrupting the joint provided by the housing 102. As shown in Figure 1, the sensors 108 may be visible from the outside of the housing 102 through windows 106.


    Figures 2 and 3 illustrate views of one of the sensors 108 and one of the windows 106 of the system 100 shown in Figure 1 according to an embodiment. An externally viewable sensor orientation indicator device 200 is visible through the window 106. The orientation indicator device 200 is a device or body that represents the orientation of the sensor 108, such as indicating the field of view of the camera disposed within of the housing 102 and obtaining images and / or videos through the window
    106. The orientation indicator apparatus 200 is shown in Figures 2 and 3 as a solid body having several indications 202 written, printed or engraved thereon. For example, the indications 202 of the letters A to E are shown along an outer edge 204 of the indicating apparatus 200. As described below, the orientation indicating apparatus 200 can move as the orientation of the sensor 108 changes The movement of the orientation indicator apparatus 200 is correlated with the movement of the sensor 108 inside the housing 102 such that, as the orientation of the sensor 108 changes, so does the position of the orientation indicator apparatus 200 in the housing 102 and in window 106.
    As shown in Figure 3, different orientations of the sensor 108 may cause different indications 202 in the orientation indicator apparatus 200 to align or be adjacent to an indication plate 206. Alternatively, the different orientations of the sensor 108 may make the different indications 202 on the orientation indicator apparatus 200 align with, or otherwise be next to a marking or other indications. Indications 202 that are aligned with, next to, or otherwise closer to the indication plate 206, represent the orientation of the sensor 108 in the housing 102. As different indications 202 line up with the indication plate 206, different orientations of the sensor 108 are indicated. For example, in Figure 3, the indications C 202 are aligned with or closer to an upper edge of the indication plate 206, thereby representing that the sensor 108 is located in the housing 102 to have an orientation and field of vision associated with the indications C 202. If the sensor 108 moved inside the housing 102 to a different orientation to have a different field of view, the orientation indicator apparatus 200 could have other indications 202 aligned with the indication plate 206, such as indications A, B, D or E 202, thereby indicating to an observer outside the housing 102 that the sensor 108 has another different orientation and field of vision.
    While the orientation indicator apparatus 200 is illustrated as a solid body that moves to indicate the different orientations of the sensor 108, optionally, the apparatus 200 5 10


    You can indicate the orientations in another way. For example, the apparatus 200 may be a sensor that detects the movement or orientation of the sensor 108 and visually shows the orientation of the sensor 108 on an electronic display or light. Although the apparatus 200 includes letters such as the indications 202, alternatively, the apparatus 200 may include other indications to indicate the orientation. For example, numbers, degrees, radians, etc. can be used. as the indications 202.
    Figures 4 and 5 illustrate a sensor movement apparatus 400 in accordance with an embodiment of the object of the invention described herein. The movement apparatus 400 is used to change the orientation of the sensor 108 inside the housing 102 from one location to outside the housing 102. For example, the movement apparatus 400 can be operated from the outside towards the housing 102 in order of moving the sensor 108 inside the housing 102 and changing the orientation of the sensor 108. This allows an operator of the system 100 to change the field of vision of a camera inside the housing 102 without having to open the housing 102.
    The movement apparatus 400 includes a pivot plate 402 to which the sensor is coupled
    108. As shown in Figure 5, the sensor 108 can be fixed to the plate 402 by fasteners 500, such as rivets, screws, etc. As shown in Fig. 4, the indicating apparatus 200 is also coupled with the plate 402, such as by one or more fasteners 500. The coupling of the sensor 108 to the plate 402 causes the sensor 108 and the indicating apparatus 200 to move when plate 402 is moved. Plate 402 is pivotally connected to an angle bracket 412 by a fastener 414, such as a rivet, screw, etc. The angle bracket 412 includes the indication plate 206 in the illustrated embodiment. Alternatively, the indication plate 206 may be separated from the angle bracket 412. As described below, the plate 402 pivots within the housing 102 relative to the bracket 412 around or around a pivot axis 416 (shown in the figure 4).
    A tilt adjustment screw 406 extends from an upper end 408 to an opposite lower end 502 (shown in Figure 5). The upper end 408 of the adjusting screw 406 is connected with an adjusting arm 410 extending upwardly inside the housing 102. This adjusting arm 410 is fixed in position in the housing 102 to prevent rotation of the adjusting screw 406 (as described below) cause the adjustment screw 406 to move up or down relative to the adjustment arm 410 (for example, to prevent the adjustment screw 406 from leaving the adjustment arm 410).


    The lower end 502 of the adjusting screw 406 extends through an opening in the housing 102 so that the lower end 502 is accessible outside the housing 102. An operator can use a tool, such as an Allen wrench or hexagonal wrench. , screwdriver or other tool, to rotate the adjusting screw 406 from the outside of the housing 102. The coupling of the adjusting screw 406 with the adjusting arm 410 prevents the rotation of the adjusting screw 406 from moving in or out of the housing 102. The adjusting screw 406 extends through an opening 418 in the plate 402. Alternatively, the adjusting screw 406 may be coupled with the plate 402, such as passing through a threaded opening in the plate 402 that engages screw 406. An inclination adjustment nut 504 (shown in Figure 5) is coupled with adjustment screw 406 in the illustrated embodiment. The nut 504 may be below the plate 402 of Figure 5 so that the rotation of the adjustment screw 406 causes the nut 504 to move up or down the adjustment screw 406 (depending on the direction of rotation).
    For example, an operator can rotate the lower end 502 of the adjusting screw 406 clockwise to cause the adjusting nut 504 to move downward in the perspectives of Figures 4 and 5. This may result in the plate 402 pivots near or around the axis 416 in a direction towards the lower side 110 of the housing 102. As the plate 402 pivots in this direction downwards, the orientation of the sensor 108 and the location of the indication apparatus 200 change. The change orientation of the sensor 108 causes the field of view of the sensor 108 to change and causes the position of the indication apparatus 200 to change with respect to the indication plate 206.
    As another example, the operator can rotate the lower end 502 of the adjusting screw 406 counterclockwise to cause the adjusting nut 504 to move upward in the perspectives of Figures 4 and 5. This may result in the nut 504 move the plate 402 to make the plate 402 pivot near or around the axis 416 in a direction towards the upper side 112 of the housing 102. As the plate 402 pivots in this upward direction, the orientation of the sensor 108 and the location of the indication device 200 changes. The change orientation of the sensor 108 causes the field of view of the sensor 108 to change and causes the position of the indication apparatus 200 to change with respect to the indication plate 206. The changing position of the indication apparatus 200 with respect to the plate of indication 206 may provide a visual indication or notification to an observer outside the housing 102 as to the orientation of the sensor 108, as described above.


    In one embodiment, a snap spring 420 coupled with the angle bracket 412 and the pivot plate 402. This spring 420 extends from the angle bracket 412 to the pivot plate 402 to provide an opposite force against the adjusting nut 504 The spring 420 generates the force to press the pivot plate 402 against the nut 504 such that the movement of the nut 504 in the opposite directions along the length of the adjusting screw 406 results in the movement of the pivot plate 402, as described above. The spring 420 can eliminate the play in the apparatus 400 and maintain the force on the apparatus 400 to ensure that the sensor 108 remains aligned or in the same orientation until the adjusting screw 406 is operated.
    Figures 6 to 8 illustrate the sensor movement apparatus 400 in a state according to an example. In the example shown in Figures 6 to 8, the adjusting screw 406 has been actuated to cause the adjusting nut 504 to move upward along the adjusting screw 406 towards the upper end 408 of the adjusting screw 406. As a result, the pivot plate 402 has rotated around the pivot axis 416 in an anti-clockwise direction to tilt the rear side of the sensor 108 up into the housing 102 towards the upper side 112 of the housing 102. In this orientation, the sensor 108 is directed downward such that the field of view of sensor 108 is directed downwardly below housing 102. This pivoting also causes the position of the orientation indication apparatus 200 to change relative to the indicator plate 206 .
    In the example shown in Figures 2 to 5, the indications C 202 in the orientation indication apparatus 200 were aligned with the upper edge of the indicator plate 206. However, the rotation of the adjusting screw 406 counterclockwise makes that the adjusting nut 504 moves up along the adjusting screw 406 and causes the plate 402 to pivot up. This pivoting movement of the plate 402 causes the indicator apparatus 200 to pivot down relative to the indicator plate 206 and, as a result, move the indications A and B 202 closer or aligned with the indicator plate 206 and the indications C, D and E 202 to move farther from and below the indicator plate
    206. As shown in Figure 8, an operator outside the housing 102 can see the new orientation of the sensor 108 since the "A" indications 202 are now aligned with the indicator plate 206. Each of the indications 202 has a notch or groove in the indication apparatus 200. When a fixed location marker (such as the upper edge of the indicator plate 206) is within this notch or groove, the corresponding indications 202 indicate the orientation of the sensor 108.


    Figures 9 to 11 illustrate the sensor movement apparatus 400 in a different state according to an example. In the example shown in Figures 9 to 11, the adjusting screw 406 has been actuated to make the adjusting nut 504 move down along the adjusting screw 406 towards the lower end 502 of the adjusting screw 406. As a result, the pivot plate 402 rotates around the pivot axis 416 in a clockwise direction to tip the rear side of the sensor 108 down into the housing 102 towards the bottom side 110 of the housing 102. This pivoting also causes the position of the orientation indication apparatus 200 changes with respect to the indicator plate 206.
    The rotation of the adjusting screw 406 clockwise causes the adjusting nut 504 to move down along the adjusting screw 406 and make the plate 402 pivot down. This pivoting movement of the plate 402 causes the indicator apparatus 200 to pivot upwardly with respect to the indicator plate 206 and, as a result, move the indications D and E 202 closer or aligned with the indicator plate 206 and the indications A, B and C 202 to move farther from and above the indicator plate 206. As shown in Figure 11, an operator outside the housing 102 can see the new orientation of the sensor 108 when the indications E 202 are now aligned with the indicator plate
    206.
    A method for indicating an orientation of a directional sensor (such as a camera) such that the indication of the orientation is visible externally with respect to a housing in which the sensor is arranged includes moving the sensor into the housing in response. to the external drive of an apparatus movement. For example, an adjustment screw can be rotated to change a sensor orientation inside the housing. Alternatively, the orientation of the sensor can be controlled remotely, such as using a remote control device and a motor that communicates wirelessly with the remote control device. In response to moving the sensor, an orientation indication apparatus can visually represent the orientation of the sensor to an operator or other observer that is external to the housing. For example, a body having indications representing different orientations of the sensor can move inside the housing and be visible through a window so that the orientation of the sensor can be determined from outside the housing. As another example, an electronic display may present the orientation of the sensor.
    An embodiment of the object of the invention described herein provides apparatus and procedures for adjusting the alignment of cameras mounted on 9 10


    dispositives. The adjustment may be an environmentally closed adjustment that also provides a visual indicator to the manufacturing or installation personnel that indicates the camera's signaling position. Being able to adjust the direction of a camera without first having to disassemble or open the case can be a big cost saving when it comes to installing the camera in the field. Orienting a camera during the start-up of a camera system can take more than an hour per unit or more, which represents a significant cost. This time is mainly due to having to partially open and disassemble the camera system once installed in the device. The objective of the invention described herein allows the installer to quickly adjust the inclination of the camera to a selected position without having to open the camera system housing, thereby significantly reducing the time required to orient the camera.
    In addition, many camera systems can be placed in the same position or orientation due to the wide similarity of installation situations. The orientation indicating devices described herein allow direct visualization of the final position of a camera by an assembler or field installer. The cameras of several systems can easily adjust to the same orientation (for example, position "B") without having to repeatedly adjust the cameras and check the images or videos obtained by the cameras.
    During a field installation of a large number of camera systems, it may be difficult to predetermine the final position of the cameras before installation. An installer can empirically start a first camera system, using the motion apparatus and the orientation indicator apparatus, and watching the output video to select a camera position. Once the position is selected, the installer can read the position of the indicating device and establish other camera systems in the same orientation, thus saving a large amount of time. The final positions of the cameras can be observed in an installation database as other information recorded during installation. If it is necessary to remove the sensor or the camera system, it is possible to quickly adjust the new sensor or the new camera systems to the positions of the previous systems and, thus, allow the field start-up values for areas target, exclusion zones, etc. remain valid.
