Multi-target three-dimensional information rapid acquisition photoelectric detection system

Abstract

The invention discloses a multi-target three-dimensional information rapid acquisition photoelectric detection system, which comprises a two-dimensional scanning reflector, an optical reflector, an infrared laser splitting element, an infrared sensor, a laser reflector and a laser distance measuring sensor, and is characterized in that the pitch angle of the two-dimensional scanning reflector is manually controlled to determine the search tracking range of the infrared sensor; the optical reflecting mirror is located right above the two-dimensional scanning reflecting mirror, the pitch angles of the optical reflecting mirror and the two-dimensional scanning reflecting mirror are consistent, and the infrared laser splitting element is located on one side of the same horizontal plane of the optical reflecting mirror. The system has the functions of infrared imaging, searching and tracking, three-dimensional information acquisition and the like of a target, multi-dimensional information such as space, heat radiation and distance of the target can be acquired at the same time in one detection period, and imaging tracking, threat judgment and the like of the target are facilitated.

Description

technical field [0001] The invention relates to the field of detection technology, in particular to a photoelectric detection system for rapidly acquiring multi-target three-dimensional information. Background technique [0002] In recent years, with the vigorous development of optoelectronic technology, there is a huge demand and broad development prospects for target detection and three-dimensional tracking at home and abroad, especially in the fields of national defense and civil aviation. At present, the tracking objects are becoming more and more diverse, and the tracking environment is also more complex and changeable, which requires the system to have good adaptability and the ability to quickly acquire multi-target 3D information. [0003] With the development of detector technology, infrared sensors have developed from linear detectors to staring array focal plane detectors, and the scanning method has evolved from traditional mechanical scanning to fast step starin...

AI Technical Summary

Problems solved by technology

After searching for multiple targets, the photoelectric detection system of the prior art needs to manually or automatically select a single target for tracking and ranging to obtain the three-dimensional information of the target. Unable to meet the needs of fast acquisition of 3D information

Chinese invention patent (publication number CN112364798A) designs a multi-target photoelectric search method and device, but only completes the multi-target search for navigation, obtains two-dimensional angle information, and lacks more important target distance information

Moreover, most of the existing photoelectric detection systems use a two-dimensional mechanical frame turntable to realize the search and tracking of the target. This method has the disadvantages of large moment of inertia and low response rate.
