Optical 3D and infrared dual-mode composite video accurate measurement monitoring system

Abstract

The invention discloses an optical 3D and infrared dual-mode composite video accurate measurement monitoring system comprising a monitoring system housing, wherein an optical 3D radar mirror group isarranged on a position at the right end surface in the monitoring system housing; an infrared detector mirror group is disposed at a position on the bottom of the optical 3D radar mirror group and onthe right end surface in the monitoring system housing; an optical 3D radar imaging circuit module is disposed at a position on the center in the monitoring system housing and on the left side of theoptical 3D radar mirror group; an infrared focal plane detector is disposed at a position on the center in the monitoring system housing and on the left side of an infrared detector; and an integratedprocessing circuit is disposed at a position close to the left side in the monitoring system housing. The optical 3D and infrared dual-mode composite video accurate measurement monitoring system notonly enables high-frame-rate 3D measurement, but also measures and monitors the surface temperature of a measured object, and integrates dual-mode data to automatically identify, track, and monitor specific targets.

Description

technical field [0001] The invention relates to an optical 3D and infrared dual-mode composite video precise measurement monitoring system. Background technique [0002] According to the principle of laser ranging, laser radar can realize 3D imaging detection. However, the early laser radar is based on point source array detection technology, point-by-point ranging, arranged in a square array to form a 3D image, the imaging speed is slow, and the points in the field of view The number of sources is small; now the linear array ranging technology is mainly used, and dozens of linear arrays form a square array, and the square array forms a 3D image. However, the imaging speed is still relatively slow, and the single-mode measurement cannot measure the surface temperature, lower resolution, etc. [0003] According to the principle of infrared radiation detection, the current infrared imaging equipment can realize "focal plane" imaging, with fast imaging speed and high resolutio...
