Binocular vehicle bottom image acquisition device

Abstract

The invention discloses a binocular vehicle bottom image acquisition device. The device comprises an acquisition box body, a first image acquisition mechanism, a second image acquisition mechanism and a control mechanism, the first image acquisition mechanism and the second image acquisition mechanism are both arranged on the acquisition box body, and the first image acquisition mechanism and the second image acquisition mechanism are both used for acquiring front image information of the bottom of a vehicle. The first image acquisition mechanism and the second image acquisition mechanism are electrically connected to the control mechanism, one of the first image acquisition mechanism and the second image acquisition mechanism is selected from a linear array camera, and one of the first image acquisition mechanism and the second image acquisition mechanism is selected from an area array camera. According to the invention, the image with good color rendition degree and high saturation degree can be obtained, and the speed is not limited to the speed of the to-be-detected vehicle.

Description

technical field [0001] The invention relates to the fields of security inspection and security protection, in particular to a binocular vehicle bottom image acquisition device. Background technique [0002] In order to effectively prevent bombs, weapons, biological and chemical hazards and dangerous people hidden under the vehicle from entering and exiting important places such as government agencies, military management, bank warehouses, station docks, customs, border inspection stations and prisons, various important places generally adopt the installation and use of vehicles. The bottom security check scans the device to check and prevent. At present, the vehicle chassis safety inspection scanning products that are ubiquitous in the market mainly include vehicle bottom inspection mirrors and single-camera vehicle bottom security inspection equipment. The under-vehicle inspection mirror requires inspectors to manually inspect the vehicle when the vehicle is stopped, and t...

AI Technical Summary

Problems solved by technology

The area scan camera has high color reproduction and better saturation. However, due to the frame rate limit of the sensor, the speed of the vehicle passing through the security inspection equipment under the vehicle is limited to below 40km / h. When the frame rate exceeds the upper limit of the camera, the scanned image will appear. Frame loss, jaggies, strip light deformation results

Therefore, the detection speed of the single-sided needle camera under-vehicle security inspection equipment will decrease; while the line scan camera can collect high-pixel images when the vehicle passes at high speed, but the collected images have poor color reproduction and low saturation
