The invention relates to computerized automation and can be used to count and measure the size of objects (of various kinds of particles, cells, microorganisms, parts on a conveyor, etc.).

The aim of the invention is to expand the functionality of the device by measuring the selected objects according to given characteristics.

Figure 1 shows the structural diagram of the proposed device; Fig. 2 shows a portion of a television image including objects of various shapes.

The device contains a television sensor 1, a quantizing unit 2, a delay element 3, a video signal selection unit 4, a block of characteristic points 5, a program-time unit driver 6, a program control unit 7, a program control unit 8, the first and second modes recorders to and 11, block 12 of the control memory, block 13 of the RAM, arithmetic block 14, the first element OR 15, the control panel 16, the encoder 17 to the second element OR 18.

The device works in the following way.

In the initial state, the mode setter 9 outputs to the shaper 6 a signal of the initial state mode, according to which shaper 6 issues the code of the initial zero-firmware microprogram address of block 13, as well as the direct load signal received through the OR elements 15 and 18 to block 8. Further under control block 8 selects a sequence of microinstructions from block 12. As part of microcommands, there are bits that control the operation of blocks 14, 8 and TZ, under the action of which the block 13 is zeroed, then, if necessary, additional Additional features: the number of points XI, the number of internal discontinuities, or their combination. The operator on the console 16 uses toggle switches to set the corresponding numbers.

. Further, when pressing the Start button of the console 16, the dial of 9 modes produces a signal formation Recording mode. In the recording mode, a number of settings are formed in the shaper .6 commands, and separately for even

and odd lines for the signals X1-X4 coming from block 5, and for the horizontal sync pulse coming from sensor 1. Under the action of these settings, information is accumulated on objects in the form of pairs of numbers in block 13, the first and second zones are intended for reindexing, in the third in the zone, when the signal X4 arrives, the number of chords of the right and left branches is remembered up, in the form of a pair of numbers.

The signal XI is used to add one to one of the general purpose registers included in block 14, used as a counter. Its contents are written to the first or second zone of block 13. By a short-circuit signal, information is read into another general register included in block 14 and used as a buffer register. Signal X2 records from a buffer register (not shown) in one or second zone. The horizontal sync pulses set the address registers of the first and second zones (two ROHs) to the initial state.

Thus, re-indexing is performed. The signals X4 are used to read the contents of the buffer register in the third zone, write information to the buffer register from the first and second zones, and read the contents of the buffer register to the third zone.

Thus, the accumulation of information about the objects.

According to the following frame pulse, the setting mode signal is generated by the setting device 9, according to which the command generator generates the installation of the main program. The algorithm of operation is as follows: allocating numbers belonging to the object, ranking them, repeating numbers (characteristic of internal discontinuities), counting different numbers (characteristic the number of tabs up), remembering all the processed numbers in order of increasing, highlighting the first number of the next object, recognizing the object in (addition; unit to one of the registers used as an object counter) 5- check if all numbers are processed, if everything is done, then a signal is generated by the control memory unit that arrives at the second input of the setting device 9 and generates the initial state signal No, and from block 14, the contents of one of the registers corresponding to the number of objects, which, under the action of the control signal from the output of block 12 of the control memory, is entered into the first recorder 10, is output, where it is recorded. The accuracy of counting and selection with such an algorithm increases.

With the arrival of the next frame sync pulse at the setpoint adjuster 9, a selection mode signal is generated at the output, according to which the command generator 6 generates an installation that reads the first number of the upper branch of the object from the first zone to one of the registers of block 14. For each XI signal generated by the block A setting is also formed, in which one is added to another register and the contents of the registers are compared. In case of equality by block 12, a start signal of block 4 is formed. Then the next, number is entered into the register of block 14. This enables selection of the video signal of an arbitrary shape object in one frame.

The video signal of the object is fed to the input of the second recorder 11, where it is measured and recorded.
