System function overview ： 

    vehicle chassis security inspection scanning imaging system is a set of automatic detection of vehicles and the vehicle chassis for image acquisition, display, splicing, capture summary, comparison alarm, automatic loop control as one of the vehicle security inspection system. The system can effectively prevent the undercarriage of bombs, weapons, biochemical dangerous goods, dangerous people in and out of government agencies, military management, bank depots, stations and docks and other important security protection places; to prevent the undercarriage of drugs and guns and ammunition and other dangerous goods, illegal smuggling of goods and even suspicious people through customs, border checkpoints, to prevent the absconding of detainees out of prisons, labor camps, detention centers, drug rehabilitation centers, etc..

2.the main features of the system:   

The use of computer vision technology to achieve high-definition, complete car chassis imaging; using high-definition color scanning imaging, automatic detection through the vehicle, the angle of view is not less than 175 °, depending on the width of the undercarriage is not less than 200CM and clear image, the output image without distortion. Support for extra-long vehicles (length is not limited) inspection, for extra-long vehicles can be dragged through the image preview window, zoom to view the entire vehicle chassis; vehicle through, the system automatically displays a high-definition complete vehicle chassis image, the size of the vehicle bottom collection information at a glance. The use of 22-inch high-definition LCD monitor can be more convenient and fast, support the optional 2-way high-definition large-screen field display monitor separately display chassis area image; can detect different models of vehicles, and display the complete vehicle chassis image on the screen; optional vice monitor alone full-screen display vehicle chassis image; can be based on the number of road crossings for multi-channel with the screen display each inspection road crossing undercarriage inspection image.

Real-time undercarriage and roof and other multi-directional monitoring functions: the maximum access to 9-channel high-definition undercarriage, roof, front, rear, left, right and other scenes of the car image; screen division mode: 1, 4, 9 optional; screen can be enlarged to display;

Scene video function: a variety of video trigger modes such as manual video, timing video, input trigger video; video playback.

Automatic detection: can be programmed on site according to user needs to realize various detection processes and achieve a high degree of automated operation. The optional license plate recognition module can carry out automatic recognition of license plates for one or two of the scene images.

Check convenient: can be in accordance with the manual or automatically enter the incoming and outgoing vehicles into the vehicle in and out of the database, when the vehicle passes through can display the relevant information of this vehicle (license plate, body color, model, etc.), through this function can greatly improve the vehicle through the speed, reduce the work intensity of inspectors. Vehicle to 1-60km / h speed through the vehicle bottom scan collection equipment, in the vehicle through < 1 second, the system automatically displays a high-definition complete vehicle chassis image. To the size of the vehicle bottom collection information at a glance, the system automatically according to the computer security inspection date to generate a corresponding folder, and will be automatically stored in the folder under the vehicle images by date and time, for future viewing. With automatic work mode, automatic capture license plate number, get chassis image function, can be equipped with intelligent analysis alarm function, can sound and light alarm; store relevant information, can query, statistics, generate reports.

Fast image processing: When the vehicle passes through the system, the scanned image is uploaded to the host in real time, and the console screen can immediately display the vehicle's real-time clear undercarriage image and historical comparison pictures, which can identify the attachment under the vehicle more quickly and accurately than the traditional method. The software is easy to operate, and the image can be scaled in whole or in part without distortion.

There is no limit to the number of zooming times, the image panorama navigation, and the image extraction from the folder does not take more than 0.1 seconds. The software can be operated to balance, brightness, contrast, saturation, sharpening of the image under the car, and local magnification of the vehicle bottom through the magnifying glass, as well as the image has the function of reading and printing. Through the previous page and the next page can be flexible access to pass through the vehicle underneath the information, underneath the vehicle image has a manual comparison function.

Record and query: the generated complete chassis photos of the car and the vehicle entry time documents are grouped into one document. You can query the complete chassis photo and entry time of each vehicle at any time by time ﹑ license plate and other information. The query results are displayed and printed in the form of reports, and the information in the database can be transferred and stored. Efficient vehicle chassis image retrieval function: you can retrieve the vehicle chassis history image data by time, license plate, model and other information.

The equipment is equipped with inductive imaging lighting control system, lighting using high-brightness, ultra-wide-angle imported surface light source devices, with super luminous, long service life, easy maintenance characteristics.

Adaptable: the system takes into account the length, width and height of the chassis of the inspected vehicles are not the same, the speed is unstable and the project construction cost and the difficulty of the site construction and other factors to ensure the reliability and flexibility of the system. Vehicle speed of 1-30 km/h uniform speed from above when the system to scan the vehicle chassis collection, the image taken real-time upload to the central control host, get the complete vehicle chassis picture. System can shoot the width of 0mm-4000mm, image clarity better than 0.5mm / pixel, the system has a strong bearing capacity (more than 30T), to ensure that the shooting mirror will not be pressed and worn. The chassis has waterproof, dustproof and anti-pressure functions.
