The problem of detection and trajectory tracking of a group of small objects by a passive vision system is solved. The system consists of several space-oriented optical receivers that monitor the viewing area is considered. We propose an approach based on the distribution of optical receivers over stereo pairs, taking into account the orthogonality of the lines of sight on objects, and the redistribution of stereo pairs in the case of receiver failures to solve this problem. An appropriate algorithm has been developed to improve the reliability of the system, the probability of detecting all objects, and the accuracy of determining spatial coordinates. The results of the experimental examination of the developed algorithm are presented.
This paper describes algorithms for detection and evaluation of trajectory parameters of small, spatially moving objects by passive optical and radio thermal vision system. The algorithms are based on spatial and temporal image processing. During spatial processing, a system of equations representing a sufficient condition for the conjugation of direction vectors to objects in stereo pairs is solved. During temporal processing vectors of the directions on accessory to objects in a sequence of the periods of supervision are distributed. The results of the algorithms theoretical and experimental examination are given. They are showing the advantage of the joint application of the two approaches.
