Aerospace Instrument-Making Annotation << Back Method of Recognition of Optical Images of Observed Space Objects Based on Discrete Dynamic Programming Klyuchkin A.K., Demchenko E.S. Space inspection is understood as a set of operations carried out using space-based equipment and aimed at obtaining information about space objects of artificial origin through observation, including when approaching them, in order to solve one of the applied problems. A feature of the use of an inspector spacecraft to solve target problems is the need for their autonomous guidance of space objects. To ensure stealth, a passive optical-electronic system is used as a measuring device in the center-of-mass guidance loop of the inspector spacecraft. A method is proposed for recognizing optical images of observation objects by on-board optical-electronic means of an inspector spacecraft, based on discrete dynamic programming, describing the contours of object images in the Freeman code, and introducing a structural metric. The corresponding algorithm for identifying astronomical landmarks is presented. Keywords: Photometric optical-electronic system, inspector spacecraft, target space object, measurement accuracy, mobile observer, observed space object, optical system, optical image recognition, on-board optical-electronic means.
