FIELD: technical physics, in particular, photometry, applicable in creation of the know-how practice of instrument estimation of the parameters of quality aerial optoelectronic aids and systems of remote sounding based on the methods of automatic processing and analysis of images of ground focus targets obtained by the optoelectronic aids in natural conditions, as well as in developments of the constructions of ground focus targets of the visible and infra-red bands of the electromagnetic spectrum.
SUBSTANCE: the method consists in installation on the ground of a trait passive focus target along and across the flight direction, accomplishment of aerial photography of the terrain with the focus target positioned on it with the aid of the optoelectronic aids at preset values of the flight altitude and course of the flight vehicle, automatic analysis of images of the ground focus and estimation of the resolution of the system performed after the preliminary processing, separation and selection of fragments with the image of the trait focus target. A universal passive focus target is used as the focus target, it provides for production of brightness and infra-red contrasts with an underlying background in the visible and infra-red spectrum bands consisting of a set of 3 to 5 trait wedges with different values of contrasts, which discretely vary in the preset band.
EFFECT: enhanced accuracy of determination of the resolution of the optoelectronic aids of remote sounding, produced a universal passive focus target providing for formation of a the brightness value of contrast at any time or of the temperature value of contrast with an underlying background.
