A generalized scheme of automated control of the apples sorting process by video signal is developed, which contains a measurement unit designed to determine the main characteristics of the investigated object on the conveyor line {d, m, g}, which allow to establish the affiliation of apples to a certain category. The process of sorting apples based on contactless measurement of such basic characteristics as size, weight, color is described. It is noted that the received information about the characteristics of individual objects is transmitted to the sorting control unit and on the basis of this information, as well as information from the block of accompaniment of apples by video signal, the automated control system (ACS) by sorting compares the time of measuring the characteristics of apples with objects that are reflected on video frames and fixes for each visual object the corresponding characteristics. This allows for the area controlled by the video signal sensor to obtain information on the characteristics of each apple from the time it hits the field of view of the video sensor and until the reset. It is proposed to select the selected types of apples from the total flow on the conveyor line, conditionally divided into a certain number of longitudinal bands, using a group of actuators, each of which selects apples from the same band of conveyor flow. The efficiency of controlling the process of sorting apples on the conveyor through the observation of the video signal, which is advisable to carry out on the basis of a pair analysis of successive frames, has been improved. At the same time tracking the trajectory of moving objects in the stream should be carried out on the basis of the calculation of the function of similarity between the reference image in the previous one and one of the set of fragments lying in the search zone on the next frame.
