Photoelectric three-coordinate search and tracking device and method

Abstract

The invention discloses a photoelectric three-coordinate search and tracking device. The device comprises a photoelectric detection assembly (1), a laser ranging assembly (2), a servo mechanism (3) and a processing assembly (4); the photoelectric detection assembly (1) searches or tracks a target when being switched to a search mode or tracking mode; the laser ranging assembly (2) is used for adjusting the pitch angle of a pitching reflector (12) according to the angular position of the target given by the processing assembly (4), directing a laser beam to the angle so as to measure the distance of the target; the photoelectric detection assembly (1) and the laser ranging assembly (2) are together mounted on the servo mechanism (3); the servo mechanism (3) is used for driving the photoelectric detection assembly (1) and the laser ranging assembly (2) to perform target search, tracking and ranging; the processing assembly (4) is used for processing image information acquired by the photoelectric detection assembly (1), extracting the angular position information of the target and controlling the laser ranging assembly (2) to measure the distance of the target.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection and laser ranging, and relates to a method of using photoelectric detection equipment to search or track a target, and a laser range finder to measure the distance of a target found by photoelectric search or a tracked target, so as to accurately and timely measure the position of the target. In particular, it relates to a photoelectric three-coordinate search and tracking device and method. Background technique [0002] Small and ultra-small drones are easy to use, difficult to control, and easy to enter sensitive areas without permission, such as civil aviation airports, which pose serious hidden dangers to the safety of aircraft takeoff and landing. Small and ultra-small UAVs are typical "low, small and slow" targets characterized by low flying altitude, small target features, and slow flying speed, and because of their low flying altitude and close distance to trees and buildin...

AI Technical Summary

Problems solved by technology

Therefore, the photoelectric warning equipment can only obtain the azimuth and elevation angle of the searched and detected target, but does not have the ability to measure the target distance. When detecting "low, small and slow" targets, due to the lack of target distance values, it is impossible to judge the threat of the target. The search efficiency of photoelectric detection equipment has dropped significantly
