Abstract

The invention discloses a tracking method based on a staring tracking one-dimensional high-speed moving target system, and the method comprises the steps: designing a high-speed moving target tracking structure, and preliminarily building the staring tracking one-dimensional high-speed moving target system; determining the position of the high-speed camera accurately according to a mirror imaging principle, so that the staring tracking one-dimensional high-speed moving target system is established; establishing a mathematical model between a galvanometer rotation angle and a picture translation pixel according to the staring tracking one-dimensional high-speed moving target system; calculating the relation between the deflection angle of the galvanometer and the horizontal pixel displacement of the gaze line of the camera according to the established mathematical model, and placing the galvanometer at the corresponding maximum deflection angle according to the appearance direction of the high-speed moving target; starting a high-speed camera to collect images in real time, and detecting whether a high-speed moving target appears in continuous images; aiming at the motion characteristics of a one-dimensional high-speed moving target, a single galvanometer mode adopted by the designed system is improved, a relatively large imaging view angle and a relatively large scanning angle can be realized, and the system has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of tracking a one-dimensional high-speed moving target, in particular to a tracking method based on a gaze tracking one-dimensional high-speed moving target system. Background technique [0002] High-speed moving targets widely exist in the fields of national defense, aerospace and sports events. Due to the characteristics of no load effect, the visual measurement method has gradually become the mainstream method for analyzing high-speed moving targets. However, accurate measurement of the moving target body requires the target to occupy as many pixels as possible, which requires a larger focal length, resulting in a smaller field of view; long-term measurement of the moving target trajectory requires the field of view to be as large as possible, resulting in A smaller focal length is required. There is a contradiction between the two. The gaze tracking system based on the reflection of the galvanometer c...

Problems solved by technology

[0003] At present, the dual-galvanometer system uses a translational galvanometer and a tilting galvanometer. First, the tilting galvanometer rotates to reflect the movement of the moving object in the vertical direction, and then the translational galvanometer rotates to reflect the movement of the moving object in the horizontal direction on the tilted galvanometer mirror. ; In this way, the dual-galvanometer system can track moving targets in a two-dimensional plane, but the imaging angle and maximum scanning angle of the dual-galvanometer system are limited due to the structure; therefore, it is necessary to design a tracking system based on staring and tracking one-dimensional high-speed moving targets method
