The drawing shows the block diagram of the device;

The device contains the second television transmitter 1, the first control element 2 delay, the first element AND 3, the generator 4 pulses, the display unit 5, the first television program 6, the sensor 7 pulses, the control unit 8 the second pery-i delay element 9, the second element And 10, the second counter 11, the first counter 12, the pulse shaper 13, the first 14 and the second 15 memory blocks.

The device works as follows.

A pair of aerial photographs are placed in front of the corresponding television transmitters 1 and 2. The left and right images of the object of study, for example, the relief of the earth's surface, are projected onto the photosensitive sites of the television transmitters. Aerial photographs are obtained by photographing the earth's surface from an airplane after a certain period of time so that # 1 40% of the surface covered by two photographs overlap each other. This zone creates a stereo effect. Each object in the stereovision zone corresponds to two iso-angiography (left and right), which are converted into corresponding video signals. In case of synchronous scanning of electronic beams of vidic television / transmitters 1 and b, the video signal corresponding to the right image of a certain object is ahead in time of the video signal taken from the output of the left television Transmitter. The synchronization of the operation of television transmitters 1 and b is carried out with a generator of 4 pulses, which produces frame and line sync pulses. At the same time, the synchronizing pulses arrive at the input of the control unit 8, which clocks and controls the operation of the device.

The output of the right television transmitter is connected to the input of the second adjustable delay element 9. The delay is varied by control block 8. Then the delayed video signal of the right television transmitter and the video signal of the left television transmitter arrive at the inputs of the first element I 3, which passes the electrical signals that coincide in time and amplitude. So Kak time shift, corresponding to 1F1Y linear parallax P, depends on the distance g from the lens base of television transmitters

 4- Jav in - base between

1 and h.eionic transmitters; f - photo image: the piece distance of the lenses., then the video signal taken from the output of the first element And 3 corresponds to the contour - isolines at a given height. At the end of the first CS1 control unit 8, the control unit sets a new delay value using the first adjustable delay element 2 and views it at a different height, etc.

The video signal from the output of the first element And 3 is fed to the imaging unit 13 of the pulse and to the display block b.

To automate the processes of quantitative processing, analysis, and documentation of the results of the study of a stereoscopic pair of imaging, the system contains blocks 7–18 with appropriate links. Sensor 7 coordinate pulses, two sequences of electrical pulses shifted relative to each other, forming the left and right images of the spatial lattice.

A spatial (three-dimensional) grating can be formed taking into account the effect of a linear perspective and superimposed on the processed (studied) stereo image. At the same time, there is no need to form a stereo image on the screen of the video control unit (WKB) 5.

Within the frame scan time, the sensor 7 pulses generates two sequences of pulses of different dimensions, the beginning of which is synchronized by the device horizontal and frame clock pulses.

To automatically extract the pulses corresponding to the flat grid imposed on the contour of the contour, a second adjustable delay element 9 and a second AND 10 element are used. for a certain time At the same time, the first .pet ylipye delay element 2 delayed the video signal of the right television transmitter relative to the left one. This ensures that the contour coincides with the flat grid. corresponding to the flat grid, arrive at counters 11 and 12.

The video signal corresponding to the contour of the isolines at a given height. take off from the output of the IZ element, and a sequence of pulses allocated by the Vindlm element I 10, arrive at the shaper 13 pulses, which forms at the output a strobe pulse when the contour video signal coincides with the pulses of the measuring (flat) lattice.

Strobe pulses, developed by pulse shaper 13, arrive at counters 11 and 12 from the outputs of the strippers, the coordinates of the points corresponding to the intersection of the contour with the grating, and in the binary-tenth code - into blocks
