FIELD: physics.
SUBSTANCE: invention relates to engineering physics and can be used in flight (full-scale) tests of aircraft optical-electronic systems and their qualimetry based on analysis and processing of images of land-based dash world of visible range. Method of determining linear resolution on the territory of an optoelectronic system of an aircraft, in accordance with which, on the ground along and across the flight trajectory of an aircraft equipped with an optoelectronic system, and using the pegs maximally stretch along the horizontal webs of the world, which are dark rectangular cloths from inextensible rubberized fabric with absolutely white strokes. Then, at a predetermined values of altitude and flight path of aircraft, aerial survey of terrain areas with located dashed worlds is performed, aerial photographs are processed and calculating the estimate of the linear resolution on the terrain of the aircraft optoelectronic system as the arithmetic mean of the estimates obtained by all decrypting operators on all images of the world, each of which is minimum width of stroke in identified groups of strokes, in which all strokes are observed separately along their entire length. At that, the world consists of set of 19 square dashed groups, each group has 3 parallel strokes of the same length and width, the ratio of the length and width of each stroke is 5:1, with the width of strokes in the sets of world 0.01; 0.02; 0.03; 0.04; 0.05; 0.06; 0.07; 0.08; 0.09; 0.1; 0.2; 0.3; 0.4; 0.5; 0.6; 0.7; 0.8; 0.9; 1.0 m, groups of lines are successively located on the web of the world in order of increasing the width of the strokes with alignment along the edge of the web, and the web is equipped with a label of radio frequency identification.
EFFECT: technical result is high accuracy of determining linear resolution on terrain of optical-electronic systems of manned and unmanned aerial vehicles.
