High-speed target detection device and method based on active illumination of reverse reflection background

Abstract

The invention discloses a high-speed target detection device and method based on active illumination of a reverse reflection background. The device comprises a detection camera, a light supplementingassembly array and a reflector made of a reverse reflective material, wherein the detection camera and the light supplementing assembly array are jointly located on one side of a target predeterminedmotion area, and the reflector of the reverse reflective material is located on the other side of the target predetermined motion area; the light supplementing assembly arrays are uniformly distributed at the optical inlet of the detection camera, and light emitted by the light supplementing assembly arrays covers a target predetermined motion area and serves as background light for target detection after being reflected by the reflector made of a reverse reflective material. The characteristic that reflected light and incident light of a microcrystalline glass material coincide is ingeniouslyutilized, active supplementary lighting is integrated at the detection end, the requirement for background'lightening 'in a special environment is met, accurate imaging of the high-speed target is achieved, and the system structure is compact.

Description

technical field [0001] The invention relates to a high-speed target detection device and method, which is especially suitable for the application environment with weak light background. Background technique [0002] How to measure the trajectory of a high-speed moving target is a difficult problem in target detection technology. The traditional high-speed moving target detection method is to use the "backlight method", that is, the background is used as the light source and the target is "shadow", and the high-speed moving target is photographed and measured. Identification device and method). The background can be in the visible light band, ultraviolet band, laser band, etc., and is used in conjunction with the detection sensor and optical system with the background light source. figure 1 Visible background is shown. [0003] The disadvantage of the traditional high-speed moving target detection method is that the shooting background must be "lighted", that is, there is ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of this application is: for the scene where the "background" cannot be lit, solve the problem that the current active supplementary light method for high-speed target detection is limited by the objective environment and has high requirements for the size of the light source
