FIELD: video surveillance; aviation.
SUBSTANCE: group of inventions includes two versions of a system for warning a pilot on collision risk and a method for warning a pilot, as well as a method of calibrating cameras. Each of the versions of warning systems comprises two chambers installed at certain heights in a certain place of the aircraft, system for providing hints in the cockpit of the aircraft, a computer system programmed in a certain way for each version. To realize the method, both chambers are actuated to create first and second video frame streams representing object images in scene and corresponding part image of aircraft, video frames are processed to calculate distance to obstacle, speed of approach and time interval before collision. Chambers are calibrated based on said video frame streams.
EFFECT: possibility to estimate time to collision for each point of aircraft.
