The invention relates to medical technology, namely to jrcTpofteTBaM for conducting biomechanical studies, and can be used in the diagnosis of diseases of the musculoskeletal system.

A device for detecting kinematic parameters of a person’s movement is known, which contains Yesha recording channels, each of which contains an optical system, an optical shutter, a photosensitive medium and a common for both channels a tape mechanism associated with photosensitive carriers, the first output and the second input of each connected to an optical shutter, the second input of which is connected to the first output of optical systems, the inputs of which are interconnected Cl.

However, when using a known device, a stereoscopic lens is performed, which involves the long preparation of the stereoscopic camera and the room where the shooting is performed

My object lighting, etc.). In addition, the photochemical treatment of the film is long and laborious; Precision processing of the acquired film materials on the stereocomparator; manual construction of motion trajectories along coordinates.

The final conclusion about the state of the musculoskeletal system (ODE) on the kinematic characteristics can

10 to be made only by visually comparing the path of movement with the benchmark of a different, previously selected, path, which in the simplest case is accomplished by overlaying the images

15 trajectories on each other and leads to a distortion of the measurement results.

The known device does not allow to quickly evaluate information about the kinematic parameters, which is especially

20 is important when obtaining results in the process of purposeful correction of the kinematic parameters of a person (for example, during photoproduction), when constant control 3a is necessary, and with the attained results of the correction. In this case, the separation in time of the process of fixing on the film of the dynamic parameters and the processing of the 5 results obtained significantly complicates the analysis of the state of QOA. The purpose of the invention is to reduce the occurrence and improvement of the quality of registration, to expand the possibilities of analyzing the diamie-to-kyus parameters of human movement. The goal is achieved in that a device for recording the kinematic parameters of human motion is inserted into each of the recording channels of a successively connected s optical switchboard, a frame forming unit, a camera and a frame selection unit, and a separately connected additional information sensor and a block for recording additional information, as well as common to both recordings {uzdihkanal№b okommutaviviaeosignalov, block illumination, television stereo paralleling control, block focusing and t ansforma- j CEC and viaeokshtrot vy block prkchem light shutters poakgaocheny to optical switches, second inputs televizdonnyh chambers popeoechineny to sew up further information blocks mapii, televyzyon first outputs connected to first ketsmer vhodayv frames isolating units to first and second inputs of the television stereocomparator A second output of television cameras is connected, and to the third one, the inputs are connected to the outputs of the unit for allocating the repers, and the television terminal is connected to the input of the scanner control unit The unit and the focus and transformation unit, the output of the scanner control unit is connected to the television camera input, the output of the focus lens is connected To the inputs of optical systems, the backlight is connected to the third inputs of the light sensor, the control unit 5, which is connected to the output of the card, and the module is connected to the output of the touchscreen module. Zai; with the second output of Ll of the TV Cameras, the second output of the optical systems, the sensor inputs of the additional PF-50. The drawing shows the structural mode of the device for registering the kinematic parameters of the last chelsea. The device contains two film and television reintegrating channels, each of which includes optical systems 1, 2, connected through optical shutters 3, 4, optical switches 5, 6, blocks 7, 8 of the formation of reference points to television cameras 9, 10. The second TV cameras 9, 10 are connected to a circuit consisting of serially connected center II, 12 additional information and blocks 13, 14 of additional information, the inputs of sensors II, 12 auxiliary information being connected to the outputs of optical systems li 2. The first The motion of the television camera 9, 10 is connected to the rapper allocation units 15, 16, and the second inputs and output of the optical shutters 3, 4 are connected to the photosensitive media 17, 18, and the second television output 9 is connected to the inputs of the television stereo comparator 19 , Ju c outputs of blocks 15, 16 of allocation of riaer. The output of the stereocomparator 19 is connected via the scanner control unit 2O by the third input of the television cameras 9, o, and through the focus 21 and focusing camera 21 to the second input of the optical systems 1.2. The tape drive mechanism 22 is connected to the second input of photosensitive carriers 17, 18, and the backlight unit 23 is connected to the third input; The video block 24 is connected to the output of the video switching block 25, the inputs of which are connected to the second outputs of the television cameras 9, 10. The device operates in a very simple way. Anatas works of the device are carried out for one film and television channel, since the second channel works in the same way. The image of contrast marks, placed on the human body (not shown), is eaten through the optical system 1, open the optical shutter 3, the optical switch 5 on the photosensitive carrier 17, which is moved by the tape mechanism 22. The exposure film is similarly exposed film and television apparatus. At the same time, through the optical commutator 5 and black 7 of the formation of the frames, the image is projected onto the target with an adjustable memory (GRP) of the camera 9. The purpose of the optical switch 5 is to separate the light in the network, the flow from the object to two photosensitive surfaces - the target of the GRP and photo stream. In block 7 of the formation of frames, an introduction into the luminous flux of special marks (bench marks) takes place, which are further used by an up-mix of chamber solutions 9 and Y. The vice signal received at the output of camera 9 Erez unit 25 for switching viaeosigchalov postuttaet viae windows T ROLL unit 24, the screen of which nablyutsayut trajectory avizheni contrast marks. At the time of termination of the aircraft, the optical shutter 3 is closed and the tape mechanism 22 stops transporting the photosensitive carrier 17, however, the GRP of camera 9 continues to generate a signal, and the image on the screen of unit 24 is maintained for 10-15 minutes {GRP signal output time) . Thus, the use of the GRP in the IS as a vndicon allows us to observe the trajectory of the movement of the contrast marks even after the end of the movement. One time recording of the trajectory is performed by recording additional information, for example, the current time, the timing of the movement dynamics, and the operation of the individual elements of the locomotor apparatus (ODE). This info {laci tiocfypada on the sensor II additional info | and then, through the optical system 1, to the photosensitive medium 17 in the form of optical symbols, as well as through the unit 13 of recording additional information on the target of camera 9 in the form of electrical signals (recording on an electrical input). It is worth noting that the movement of the trajectories of the contrast marks can be performed without the participation of a photosensitive medium on the screen of block 24, which occurs during, for example, prosthetics, when the final result is not important and intermediate results may not be fixed. When it is necessary to compare the results of prosthetics or Research with a standard (or other chosen trajectory), a kinoplet processed by a photochemical method is replaced with a photosensitive carrier 17 and after receiving the trajectory 9 on the MIR camera of the studied trajectory using film 23 under the optical module the switch 5 and block 7 of forming the frames on the target of the GRP of camera 9, where it is superimposed on the trajectory, and on the screen of the video monitor 24 ayuts two superimposed trajectories standards (vgbranna) and issleouema. Since it is stereo-television, the installation is quite sensitive to the unregistration of television rasters and the right channels of cameras 9 and 10, in

The device has entered the previously mentioned frame forming units, as well as the frame selection units. The frames introduced into the light flux are projected onto the targets of the GRP chambers 9 and 10 and then separated from video 1x: ignaps with the help of blocks 15 and 16 of the selection of frames. Any temporal misalignment of video satellites of rappers characterizes the displacement of rasters relative to each other, which can be determined using stereo television comparator 19 and corrected by the sweep control unit 20, which is controlled by the stereo comparator 19 mismatch signal. When the rasters are combined, any video mismatch carries the information about the spatial position of the contrast signals . labels, therefore, the processing of video signals using the television stereocomparator 19 does not determine the spatial position of the object. This information was analyzed by analyzing the state of the ODE, as well as for controlling the focusing and zooming unit 21, which provides dynamic focusing and a continuous scale independent of the object being approached or removed. With the help of the telej Joynog stereocomparator 19, it is possible to determine the spatial position of the object, information about which was compacted on a photosensitive medium 17 (for example, a film). For this, a photochemically processed film with a pitch of block 23, switch 5 and block 7 is projected onto the target of the GRP of the camera 9. The Vidicon with adjustable memory is switched to the low voltage mode of the signal plate, and there is no effect of storing the TV signal. The resulting television signal from cameras 9 and lOnt is given on a stereo hedgehog 19, the output of which produces information about the spatial position of the object, kotfa can be used for further analysis. The device provides a reduction in the recording time of the trajectory of movement of the contrast marks, since the need for intermediate recording of the results on the film is eliminated, and only the final results of the study, such as prosthetics, are recorded on the film. In addition, as a result of the use of two photosensitive carriers, a film and a vidicon with adjustable memory, the comparison of the obtained trajectories with the reference one is greatly simplified.
