Laser-assisted vehicle information shooting device and shooting method

Abstract

The invention relates to a laser-assisted vehicle information shooting device and a shooting method. The device comprises a casing, wherein a number plate camera, a band pass filter, a panoramic camera, an infrared laser illuminator and an electronic control unit are mounted in the casing; the panoramic camera adopts a color-to-black camera equipped with an infrared cut-off filter and an infrared transmission laser filter; the band pass filter assists the number plate camera in recognizing number plate information; the infrared laser illuminator provides assisted infrared light supplementary lighting for the panoramic camera and the number plate camera; the panoramic camera and the number plate camera transmit image information to the electronic control unit which processes the information to obtain vehicle and number plate information. According to the provided laser-assisted vehicle information shooting device, the vehicle information, the number plate information and facial features of front-row driver and passenger in a vehicle are recognized by means of the infrared laser illuminator and double cameras, dazzling is avoided for a driver in a recognizing process, and potential safety hazards caused by hard light in the prior art are eliminated.

Description

technical field [0001] The invention relates to the technical field of laser active lighting and imaging, in particular to a laser-assisted vehicle information capture device and capture method. Background technique [0002] With the development of the intelligent transportation industry, there are more and more traffic monitoring and illegal behavior capture devices. These devices provide convenience for the traffic management department. They can check the traffic conditions in real time, control vehicles, and carry out illegal behaviors 24 hours a day. detection and capture. Combined with a high-definition camera, the shape, color, license plate number, and facial features of the front row drivers and passengers can be seen clearly through the supplementary light of the bright white flash, which provides good evidence for the traffic management department and the public security department to investigate and solve the case. [0003] However, while these high-tech devices...
