Экспериментальное исследование оптических фильтров для систем технического зрения

Abstract

The existing physical and software tools for image filtering are Analyzed. A narrow-band antireflection filter with a wavelength of 850 nm has been developed. An algorithm for the combined use of software and physical filters to improve the accuracy of the vision system is proposed. Experimental studies were conducted to test the proposed method. The use of narrow-band optical filter in combination with software filtering and smoothing allow to increase the accuracy of determining the coordinates of infrared beacons on the frame, which in turn allows for automatic landing of unmanned aerial vehicle via infrared beacons with an accuracy of 30 cm for multicopters with vertical boarding in the absence of signals of satellite systems. The offer can also be used as protection against intense laser radiation of technical vision systems for guidance, targeting and tracking.
