The use of intelligent cameras and sensors, in combination with the human operator in video analytics systems, from which most of the analytical and visual load has been removed, allows you to increase the efficiency of video surveillance and, as a result, increase the safety and productivity of work in production as a whole. Analysis of the existing data processing methods in the video surveillance systems of industrial facility showed that the use of a non-contact method for analyzing person’s posture and actions in the camera’s field of vision is rare, but it can be critical in certain situations (person in overalls is in the camera’s field of view, but the system is on him does not respond, because he is not in the forbidden zone). The improvement of algorithms for the intellectual analysis of video data in the system for monitoring compliance with industrial safety rules (analysis of the type of dynamics and control “friend or foe”) using neural network processing technologies is considered. Effectiveness evaluation of algorithms for analyzing full-scale video data software implementation showed the correctness of classification in 97% of cases. Effectiveness evaluation of the 5 subjects into two classes of “own” and “alien” classification was carried out by cross-validation and showed an accuracy of 99% on the test sample.

Keywords:video analytics, intelligent analysis, dynamics type recognition, neural network, classifier, pose determination.
