FIELD: physics.
SUBSTANCE: invention relates to engineering physics and can be used for qualimetry of aviation digital optoelectronic systems during flight tests. Method consists in placing on the ground along the horizontal line the dashed worlds of the visible range, performing the aerial survey of the terrain sections with the located dashed worlds at the a priori specified values of the altitude and the flight course of the aircraft, decoding of obtained digital aerial images by at least three decoder operators, determining the actual modulation contrast of the dashed lines based on the results of measurements on the area of the brightness of the light and dark lines of the dashed lines, displaying on a software system for visualizing and processing images of selected digital aerial photographs with an image of the line world and their interpretation. At that, interpretation of the line map images and determination of the recognized group of lines is carried out in an automated mode using the image visualization and processing software system based on the criterion of threshold contrast of the line map image, corresponding to visual recognition of a group of dashed targets for given conditions and determining the recognized group of dashed targets, calculating an estimate of the linear resolution on the terrain of the optoelectronic system of the aircraft as the arithmetic mean of the values of estimates, each of which is equal to the distance between adjacent light strokes determined on the image in the recognized groups of the dashed target.
EFFECT: providing the possibility of automating the process of identifying a line target without participation of a decoder operator when determining linear resolution on the ground of optoelectronic systems of aircraft.
