CS259017B1 - A method for visual inspection of object defects and apparatus for performing the method - Google Patents

Abstract

The invention belongs to the field of television. The aim of the invention is to reduce the time of fault determination. This method, based on converting the image of the object into a monochromatic television (TV) signal with a fixed number of decomposition elements, quantizing the TV signal by level and color coding of the obtained signals with its further display, after conversion each frame of the TV signal is divided into equal sections with a specified number of elements, adding the lengths of the pulses quantized by the level of the TV signal in each section of the TV signal frame and its further conversion into a TV signal before color coding. The device includes a TV signal shaping circuit I, an amplitude discriminator II, a time interval meter III, an adder IV, a memory block V, a color coding block VI, a color video control block VII, a measuring grid shaping circuit VIII and a spatial discretization zone shaping circuit IX.

Claims (2)

OBJECT OF THE INVENTION 1. A method of defining object defects, based on converting an object image to a monochrome television signal (TV) with a plurality of decomposition elements, quantizing the television signal according to the level and color coding of the obtained signals, by distinguishing it in order to after defect determination time, after converting the object display to a monochrome television signal, each frame of the television signal is distributed over equal sections of a specified number of elements, adding the pulse lengths of the quantized television signal in each section of the television signal, further converting it to a television signal in front of the color signal coding. 2. Apparatus for carrying out the method of claim 1, comprising a TV signal shaping circuit and a series-connected memory block, a color coding block and a color video block, characterized in that a series-connected amplifier discriminator is connected, the input of which is connected to the signal output of the shaping circuit A TV signal, a time interval meter and a summator, the output of which is connected to the information block of the memory block, and the second input is coupled to the memory block output, that the wiring of the measuring grid circuitry is a spatial discretization circuit, the inputs of which are connected to the synchronizing output of the TV shaping circuit a signal, wherein the first output of the grating measuring circuit is coupled to the control input of the amplitude disintegrator, and the second output is coupled to the control input of the spatial discretization zone, the first output of which is connected to the memory input of the memory block i, and the second output - with the time meter input control. 259017
