Method of Optical Information Support for Detecting Artifacts by f Robotic System in the Infa-red Range on a Complex Background

Abstract

A method is proposed for opto-information support for detection in the infrared range using a passive optoelectronic system of an unmanned aircraft against a complex background formed by atmospheric radiation in the far infrared range (8–13 ?m). The atmospheric background against which an unmanned aerial vehicle is detected is formed by the radiation of the cloudy atmosphere when observed from the earth's surface. Of particular interest is the complex background created by cumulus clouds of various magnitudes or other classes of clouds that have breaks. The following assumptions are made: a short-focus optical-electronic system has a wide field of view, video information about the artifact and the background characteristic is presented in binary form. The processed video stream is a two-dimensional array, the elements of which contain information about the level of radiance of the radiation in the selected direction. The emphasis is on the need to monitor changes in the structure of the emitting background and the absence of the need to process each frame of the video stream.
