    The processor unit is arranged to receive images taken by the image pickup unit so that the processor unit can detect the two or more markers. The processor unit is adapted to detect a visible identity of at least a first marker of the two or more markers, and to perform a motion analysis of a movement of two or more of the markers based on the detected visible identity of at least the first marker.
    Since a motion analysis is performed based on the detected visible identity of at least the first marker, a user of the arrangement can easily perform a particular motion analysis by selecting at least one marker. Thus, the motion analysis arrangement is easy to use.
    Through this, the above-mentioned purpose is achieved.
    According to some embodiments, the processor unit is arranged to detect a visible identity of a second marker of the two or more markers, and arranged to perform a tube travel analysis of a tube journey of the two or more markers based on the detected visible identity of the first marker and the the second cursor.
    Through this, the processor unit can be adapted to detect visible identities of a combination of markers and to perform a motion analysis of a movement of the two or more markers based on the detected visible identities of the combination of markers. Such a combination of markers can be based on any number of markers, for example two, three, four, five, six, seven, eight, nine, ten, eiva, or twelve markers. The markers can have mutually the same or mutually different visible identities in any combination. For example, in a set of three markers, each of the three markers may have mutually different visible identities, the processor network being adapted to perform a certain motion analysis of a motion of the two or more markers based on the detected visible identities of the three the markers. In addition, in a set of three markers, each of the three markers may have the same visible identity, the processor unit being adapted to perform a certain motion analysis of a motion of the two or more markers based on the detected visible identity of the three the markers.
    In addition, there may be markers that do not form part of the arrangement. in a set of, for example, eight markers, the processor unit may perform a motion analysis of a motion of five of the eight markers based on the detected visible identity of two of the eight markers. Alternatively, the processor unit may perform a motion analysis of a motion of the two or more markers, based on the detected visible identity of at least one marker.
    The visible identity of the two or more markers may comprise a structure, and / or a color and / or a symbol, and / or a shape so that the processing unit can detect the visible identity of at least a first marker of the two or more markers. The visible identity of a marker can be unique or it can be the same as a visible identity of one or more markers.
    Because markers with a visible identity are used, the processor unit can easily distinguish the markers used. Thus, advanced and resource-intensive algorithms and / or several secondary recording devices do not need to be used. According to certain embodiments, the arrangement comprises only an image capture unit, for example a camera.
    The processor unit may be included in a computer, such as a laptop, or in a mobile phone, or in an electronic reader, or in a tablet, or in a game console.
    The processor unit may comprise one or more processor units such as one or more processors. The image capture antenna may include a capture device / camera. The camera can be, for example, a digital camera, a webcam or a high-speed camera.
    The image capture unit may be connected to the processor unit by a cable or a wireless connection so that the processor unit may receive images taken by the image capture unit. In addition, the images can be received in the processor unit in the form of a signal transmitted by the image pickup unit. The processor unit can then process the signal to thereby detect the visible identity of at least the first marker. The processing may include algorithms adapted to detect said visible identity. Then, based on the detected visible identity, the processor unit can perform the motion analysis.
    The arrangement can for example be used for activities in sports, training and rehabilitation and / or in industrial applications for performing motion analyzes of machines, robots, tools, etc. In addition, the arrangement can be used for computer games.
    The motion analysis may include a motion analysis where the movement and / or rotation of one or more markers is analyzed. The tube travel analysis may comprise a size measurement and / or a measurement of a shape of one or more markers. The motion analysis can include one or more of: angular measurement between markers, angular velocity between markers and / or velocity measurement between markers and fetler velocity measurement of one or more markers, distance measurement to one or more markers and / or distance measurement between two or more markers. In addition, a motion analysis may include one or more calculations with the movement of one or more markers as input data in one or more of the calculations.
    According to some embodiments, the motion analysis may include a static analysis. The static analysis may comprise one or more of: a size measurement and / or a dimensional measurement of one or more markers, an angle measurement between markers, a distance measurement of one or more markers and / or a distance measurement between two or more markers, an angle measurement of one or multiple markers.
    According to certain embodiments, the arrangement comprises a memory in which a plurality of motion analyzes are stored, and the processor unit is arranged to, based on the detected visible identity of at least the first marker, wet one of the saved tube analysis analyzes. Hereby, the processor unit can be adapted to select one of the stored motion analyzes based on the detected visible identity of at least the first marker, the selected motion analysis being performed by the processor unit. The memory may be a computer memory included in the processor unit or a memory not included in the processor unit, such as a memory offering the processor unit remote access to the memory, for example via the Internet.
    According to some embodiments, at least one of the plural motion analyzes comprises a calculation of a value representing a force, and / alter a moment and / or an impuis. Such a calculation may be based on weight specifications and / or the moment of inertia of an object which a user feeds into the processor network.
    Thus, a user can enter weight data and / after moments of inertia for an object intended to undergo a motion analysis, to the processor unit. The processor unit can then calculate a value representing a force, and / after a moment, and / or an impuis based on the weight data and / or the moment of inertia and the movement of the object.
    In some embodiments, at least the first marker comprises a flat surface. According to certain embodiments, all markers included in and utilized in the arrangement may include a piano surface each. The term flat surface is intended to include a surface having an extension in only two directions. An angle of a cursor relative to the imaging unit affects the shape of the cursor as detected by the imaging unit. Therefore, when the arrangement comprises and utilizes two or more markers having a flat surface, a measured shape of one or more markers may be used to calculate an angle of the marker. According to certain embodiments, at least the first marker comprises a flat surface, wherein at least one of the motion analyzes of said plurality of motion analyzes comprises an analysis of a change in size and / or a change in shape of the flat surface on images taken by the image capture unit.
    In addition, a measured size or a measured change in the size of a flat surface of a marker can be used to calculate a position of a marker or a change of the train of a marker. Consequently, when the arrangement comprises and utilizes one or more markers having a pian surface, a calculation of a movement in three dimensions can be achieved despite the utilization of a single secondary recording unit. The use of only one image capture device reduces the cost of the arrangement and simplifies the use of the arrangement.
    According to certain embodiments, the arrangement comprises a feedback unit arranged to receive a performed tube analysis, after a result of a performed motion analysis, from the processor network, and to present the performed motion analysis, or the result of a performed tube analysis, to a user. The feedback unit may comprise a display such as a computer screen, LED screen, piasm screen, a projector and / or one or more audio devices such as speakers. Thus, a performed motion analysis, or a result of a performed tube analysis can be presented to a user in the form of visible information and / or audible information. The movement analysis performed, or a result of a performed tube analysis can include visible information and / or audible information that indicates to a user how a movement is performed. In some embodiments, the processor unit may compare a motion analysis, or the result of tube analysis, with a reference motion. In such embodiments, a performed motion analysis, following a result of a completed motion analysis, may contain visible information and / or audible information indicating to a user whether a motion is within a range of a reference motion.
    In embodiments where the arrangement is used for training purposes, the visible information and / or audible information may indicate to a user whether a certain exercise is performed correctly in relation to a reference movement, e.g. performed by a professional trainer.
    According to certain embodiments, the feedback unit comprises a disptay which is arranged to display a performed motion analysis, or the result of a performed motion analysis. The motion analysis shown, or a result of the motion analysis performed, may include a visualization of a movement of one or more markers.

Such a display may be a display arranged to show a motion analysis performed, or a result of a motion analysis performed. Images taken with the image capture device and a motion analysis performed, or a result of a motion analysis performed can be displayed to a user.
    According to certain embodiments, the feedback unit comprises loudspeakers which are arranged to present an audible representation of the performed motion analysis, after a result of the performed tube analysis, to a user. The audible representation may include sounds that indicate to a user how a movement is performed. In some embodiments, the processor unit may compare a tube travel analysis, or the result of a motion analysis, with a reference motion. In such embodiments, the audible representation may include sounds indicating to a user if a movement is within an interval of the reference travel. In embodiments where the arrangement is used for training, the audible representative tone may indicate to the user whether a particular exercise is performed correctly in relation to a reference movement, e.g. performed by a professional trainer.
    According to certain embodiments, the motion analysis comprises a motion tracking of one of a marker. Thus, a motion analysis may comprise a tracking of a movement of a marker.

    The object may comprise a person, an animal, a machine, a robot, a crane or any other object on which a user intends to perform a motion analysis.
    As stated above, the arrangement can be used to perform a motion analysis of an object in the form of a person. In such embodiments, the arrangement may be adapted to perform movement analysis by a person for sports, training and / or rehabilitation purposes. Even in these embodiments, the arrangement is easy to use because the arrangement only needs to use a secondary recording unit, and at least a first marker whose identity when detected can trigger a tube travel analysis. The arrangement may include several markers with different identities. A specific set of markers may correspond to a specific training activity so that a user may select a set of markers to thereby trigger a tube travel analysis corresponding to the selected training activity. Such training activity may include bicepscuri, triceps curl, squats, bench press, squats, pole vault, pole vault, cycling, running, rowing, cross-country skiing, etc. For example, if a user intends to perform a bicepscurl training set, the user may select a set of activities. markers that belong to biceps curl training activities. A manual in electronic form or in printed form can inform the user about which markers can be used in connection with a particular exercise. lVlanuaien can also inform the user how to attach the markers, e.g. at which part of the body each marker should be placed.
