Police transparent window imaging reconnaissance system

Abstract

The invention discloses a police transparent window imaging reconnaissance system, which comprises a host and a video display terminal. The police transparent window imaging reconnaissance system is characterized in that the host comprises an infrared laser provided with a laser beam expander, a camera compound lens provided with an infrared enhancing CCD, a digital processor DSP and two single chip microcomputers, wherein the video display terminal comprises a display and a controller, the infrared laser emits infrared rays with particular wavelength after beam expanding homogenization treatment for irradiating a reconnaissance target, the infrared rays are subjected to enhanced imaging by the infrared enhancing CCD via the camera compound lens, acquired video signals are processed by the DSP via a video acquisition decoder, the processed video signals are output to the display of the video display terminal through a video decoding chip via the first single chip microcomputer for real-time display, meanwhile, the DSP sends three paths of control commands through the second single chip microcomputer, so as to perform feedback control on the camera compound lens and the infrared enhancing CCD by regulating spot size through the laser beam expander, and to regulate optical axises to be uniform; and the controller of the video display terminal outputs control signals to be connected with the second single chip microcomputer.

Description

technical field [0001] The invention relates to a police reconnaissance device, in particular to a police reconnaissance system for performing photoelectric perspective imaging on the inside of glass in a closed room, dark glass, and various vehicle windows (including film sticking). Background technique [0002] Due to the urbanization process and the popularity of transportation, many criminal activities occur in closed rooms and traffic vehicles. Due to the dark interior environment and the vehicle glass film, the glass surface forms a mirror surface, which leads to strong chiaroscuro and reflections. and reflections, so that investigators cannot observe its interior through the glass window, because traditional means (direct observation with human eyes, telescope observation or conventional photoelectric imaging equipment observation) cannot achieve window imaging through glass, and it is difficult for public security personnel to deal with this problem. The detection wo...

[0002] Due to the urbanization process and the popularity of transportation, many criminal activities occur in closed rooms and traffic vehicles. Due to the dark interior environment and the vehicle glass film, the glass surface forms a mirror surface, which leads to strong chiaroscuro and reflections. and reflections, so that investigators cannot observe its interior through the glass window, because traditional means (direct observation with human eyes, telescope observation or conventional photoelectric imaging equipment observation) cannot achieve window imaging through glass, and it is difficult for public security personnel to deal with this problem. The investigation of a class of criminal activities brings difficulties, so there is an urgent need for an investigation system that can realize the imaging function of glass through windows
