METHOD OF AEROPHOTOGRAPHY OF TERRESTRIAL OBJECTS IN CONDITIONS OF INSUFFICIENT LIGHTING WITH HELP OF UNMANNED AIRCRAFT Russian patent published in 2018 - IPC G01C11/02 

FIELD: photography.

SUBSTANCE: invention relates to imaging devices specially adapted for photographic survey of a locality. Declared method of aerial photography of ground objects in conditions of insufficient illumination (at night) with the help of unmanned aircraft provides for the use of an unmanned air complex (UAC) which includes two unmanned aircrafts (UAs) operating on a joint flight with diverse synchronously operating loads: UA-1 – with a digital camera; UA-2 – with a flash.

EFFECT: technical result is to ensure the preservation of the duration of the potentially useful flight time of the UA with a digital camera (UA-1), to increase the flight altitude from which photography is performed, to increase the reliability of photo interpretation by using the unmasking features of objects – the shadows of objects with camouflaged coloring (under the condition coincidence in the visible range of values of the albedo of objects and the underlying surface), in order to avoid the possibility of the radiation receiver being illuminated (matrix) digital camera reflected backwards flash emission, due to its scattering by aerosols and hydrometeors, to make it possible to use it as planned and aerial perspective.
