The invention relates to phototopography, in particular to photogrammetry.

A known system for decrypting photographs comprising blocks of zone images, synthesis, and photographic recording.

A disadvantage of the known system is the inability to transform the coordinates of the points of the synthesized image into the coordinates of the points of the map.

A well-known photo decryption system comprising series connected zone image unit and synthesis unit.

A disadvantage of the known system is the inability to transfer decrypted synthesized images to a card. . :.

The aim of the invention is to increase the reliability of decryption by jointly processing photo images and predetermined conventional signs.

This goal is achieved by the fact that a sequentially connected optical-electronic digital converter, a block for combining zonal images, a resolving unit and a display, and also a unit for determining coordinates the output of which is connected to the second inputs of the block combining zonal images and the decision block, a control panel, the output of which is connected to the third input of the decision block and plotter whose input is connected to the second output deciding unit, wherein the inputs of opto-electronic-digital converter unit for determining coordinates are respectively connected to first and second outputs of the synthesis unit and the output plotter connected to fourth input deciding unit.

The drawing shows a structural diagram of the system.

The system comprises a zone image unit 1, a synthesis unit 2, an optical-electronic digital converter 3, a coordinate determination unit 4, a zone image combining unit 5, a decision unit 6, a control panel 7, a plotter 8 and a display 9.

The system operates as follows.

The block of zone images 1 forms and colors black and white images. In block 2 synthesis on the common screen

zonal photographic images are combined and a synthesized photographic image is formed. The operator controls the image on the screen of the synthesis unit. By setting

Compliance of the image synthesis obtained in block 2 with the existing requirements, it fixes on the plotter a cartographic base with applied reference points and from the control panel 7

enters the numbers and positions of these reference points in the coordinate system as the main one in the decision block 6. Then, on the synthesized image, the operator, using the coordinate determination unit 4, measures the coordinates of the reference points — and transfers them to the decision block 6, where according to the coordinates of the corresponding reference points of the cartographic base and the synthesized image computes the parameters

transforming the synthesized image. This ends the first mode of operation of the system and the operator proceeds to work in the second mode, when the coordinates from

objects decoded on the synthesized photo image by the joint work of the coordinate determination units 4, the optoelectronic digital converter 3 with the subsequent formation

the generalized signal in the zonal image combining unit 5. This information

06 object is entered into the decision block b from the block 5 combining zonal images, and from the remote control 7 operator

enters the corresponding symbol into the coordinates of the object, and the generalized signal processed taking into account the transformation parameters is displayed on display 9 to control decryption and possibly.

th editing. When determining the presence of quality work, the operator from the remote control

7, the control sends an enable signal to the system for the last operation — mapping on the plotter 8. This completes the operation of the decoding system for the synthesized images.

Using the invention will increase the reliability of the results of recognition of images of objects, increase labor productivity in connection with the creation of a semi-automatic mode of operation of the structure and the possibility of parallel operations to decrypt the synthesized images and edit the decryption results.
