What is the working principle of the under vehicle imaging system?

PL-UVIS 222 Under Vehicle Inspection System is the fixed solution for the fully identification of threats or modifications to a vehicle’s undercarriage. It can quickly and accurately identify threats , contraband objects and stowaway who are hidden at the bottom. Vehicles drive over the embedded scanning units while Polimek’s systems compile high-resolution images of a vehicle’s undercarriage to create the vehicle’s “fingerprint.” It’s easy to see any threatening objects that may be hidden on top of an axel or crossbeam. An overview/driver camera captures the normal view of car/driver and displays this on the high-resolution monitor .

1. Under Vehicle Inspection Camera Features Advantages:

• Auto digital line scan, high-resolution undercarriage imaging.
• Decision Response Time: 2-3 seconds
• Applicable to variety of vehicles, wide vision.
• Multi-Language Interface Design.
• IP68 high degree of protection, anti-seismic,adapting to any climate environment.
• Test will be completed during the vehicle maneuvers without stopping, adapted to different speed.
• Strong expansion capability, can easily achieve all kinds of linkage control(such as anti-collision system, barrier,etc.).
• Multi entrance management model, and statistics of entering and exiting vehicles.
• Flexible detection process can be made on site to satisfy the needs of various work conditions.
• Image monitoring, video recording for different scenario
• Undercarriage image can be stored, retrieved, searched or compared with other images.
• Whole image display ion monitor, can zoom, playback, sign in the images, stretching and cutting, etc
• The image is automatically stored, deleted: Save not less than 10,000 pictures, expired pictures will be deleted automatically
• Linear CCD scanning technology dynamic imaging; Scanning Mode: linear scan, ground coil trigger
• No need to park vehicle, can bear speed below 30km/h
• Time of image display after scan <1s
