Short-distance flying target attitude measurement system

Abstract

The invention provides a system used for short-distance flying target attitude measurement. The system comprises front-end starring systems and a rear-end processing and storage system, and an optical fiber transmission system connecting the two systems. The rear-end storage and operation system transmits an instruction before a flying target flies by or hits the bull's eye, and the instruction is transmitted to each front-end starring system via optical fibers. The laser lighting equipment and the high-speed video cameras of each starring system start to work. The photographed images are transmitted to the rear-end storage and operation system to be saved in real time. Multiple video cameras photograph the flying target at the same time in short distance. Parameters of attitude, speed, position and miss distance in hitting the bull's eye of the flying target can be measured according to certain known calculation methods. The front-end starring systems used for short-distance photographing are low in cost and particularly suitable for certain flying targets with destructiveness. The front-end starring systems within destructive range in miss distance explosion are allowed to be damaged and can act as consumables to be replaced and then the whole system can continuously work.

Description

technical field [0001] The invention belongs to the technical field of attitude measurement of flying objects, in particular to a system for measuring the attitude of flying objects in short distance. Background technique [0002] In the shooting range measurement, there are mostly fast, small and many flying targets. Generally, flying targets need to measure parameters such as position, speed, attitude, and miss distance. They are small and fast, and it is difficult to measure all-weather flying targets. It is a technology collection that integrates optical imaging, servo tracking, high-speed video recording, high-speed storage, and mathematical analysis. [0003] One method is the theodolite tracking measurement method. The tracking equipment is arranged in a safe area, and the flying target is imaged from a long distance and followed by the target camera. It is very difficult, as mentioned in Wang Min's "External Field of View Stitching Measurement Technology and Its Rea...
