Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] The infrared radiation / reflection imaging of moving targets may be concentrated on long-wave or medium-wave, or short-wave, or both short / medium / long-wave, so it is biased to only rely on long-wave or mid-wave infrared imaging to intercept moving targets , especially for weak and small targets in the distance, make full use of multi-band imaging to obtain its energy distribution in multiple bands, which is conducive to the capture of weak and small targets, and then perform precise measurement of the full infrared spectrum.

[0018] The invention divides the spectroscopic mirror into the cen...

Abstract

The invention discloses a multi-waveband infrared imaging spectrum collaborative detection system. In a spectrum correlation detection system optical path of the system, the region beside the center small hole of a spectroscope totally reflects wide spectral infrared energy, short-wave infrared / medium-wave infrared / long-wave infrared imaging modules are respectively constructed, a dynamic targetcapturing subsystem with three-waveband infrared fusion is formed, and the imaging detection capability of a moving target is improved. Meanwhile, full-spectrum infrared energy transmitted by the central small hole of the spectroscope reaches an infrared wide spectrum detection module for measuring a target in the center of the view field or a background infrared spectrum to form a spectrum measuring sub-system. These subsystems and servo control, multi-waveband image processing and infrared spectrum processing modules form an infrared spectrum collaborative detection and recognition system with strong dynamic target detection and recognition capability.

Description

technical field [0001] The invention belongs to the technical field of infrared remote sensing and image recognition, and more specifically relates to a coordinated detection system for multi-band infrared imaging. Background technique [0002] The existing infrared spectrum correlation detection system uses single-band infrared imaging to capture moving targets, and then pulls the imaging target to the center of the field of view for spectrum measurement. The existing problem is: the ability of single-band imaging to capture moving targets is limited, if the weak target cannot be captured by single-band imaging, then its spectral measurement cannot be realized. Contents of the invention [0003] In view of the defects of the prior art, the purpose of the present invention is to provide a coordinated detection system for multi-band infrared imaging, which aims to solve the problem that the detected target has weak energy in a single infrared band and is difficult to detect...
