Active closed-loop control type synchronous high-speed target following shooting device and method

Abstract

Provided in the invention is a following shooting device comprising a high-speed shooting and recording system, a large-view-field passive detection system, a following shooting trigger signal emission system, an image stabilization compensation platform and a control and data storage processing system. The high-speed shooting system comprises a high-speed following shooting camera and a fast oscillating mirror. When a target transmitting command is sent out, a trigger signal is synchronously transmitted to the following shooting trigger signal emission system; the trigger signal simultaneously controls the high-speed shooting and recording system and the large-view-field passive detection system to start working; the large-view-field passive detection system outputs a target correction signal to the fast oscillating mirror and the image stabilization compensation platform in real time to complete real-time correction of the angle of the fast oscillating mirror and fine adjustment of the detection view field of the large-view-field passive detection system; and after data acquisition and reception, a final image is analyzed and acquired through the control and data storage processing system. According to the following shooting device, closed-loop control over the fast oscillating mirror is achieved, the angle of the fast oscillating mirror is corrected in real time, and the shooting success rate and shooting quality can be greatly improved; and the following shooting device has the advantages of being high in precision, resistant to interference, high in adaptability and the like.

Description

technical field [0001] The invention relates to the field of high-speed target tracking and recording, in particular to a closed-loop control high-speed target synchronous tracking device and method using active light detection to feed back target position information in real time. Background technique [0002] The tracking and recording of high-speed targets is in urgent demand in both military and civilian fields. At present, the detection technology of the high-speed target synchronous tracking and recording system that meets the needs of this application is relatively mature. The detection method is based on open-loop control, and the high-speed target tracking and recording is completed through the combination of a high-speed camera and a fast-swing mirror. Such as figure 1 As shown, among them, figure 1 (a) recording equipment for high-speed target tracking, figure 1 (b) is the working mode; this follow-up method arranges two canopy targets at the target exit, and i...

AI Technical Summary

Problems solved by technology

[0005] (1) It is difficult to arrange the sky screen target in some special environments, and the projectile velocity signal measured through the sky screen target requires high accuracy, otherwise it may cause a large error in the matching between the fast-swing mirror motion trajectory and the projectile speed, which will affect the shooting quality. Poor or missing targets;

[0006] (2) The error generated by the trajectory of the fast-swing mirror calculated according to the theory may also cause a large error in the matching between the trajectory of the fast-swing mirror and the speed of the projectile, resulting in poor shooting quality or loss of the target;

[0007] (3) The adaptability of the carrying platform is weak, unable to adapt to some special carrying platforms (for example, it is difficult to achieve accurate tracking of moving targets at sea on platforms such as ships), and it is easily disturbed by external environmental factors
