Advanced Under Vehicle Scanning Solution(UVSS)
that efficiently and safely controls the vehicle’s undercarriage.

TREX-UVSS uses the latest technologies of industrial high-resolution digital cameras, LED illuminations and image processing algorithms. The system comes with a sophisticated Software Suite with an intuitive and customizable graphical interface.

As a vehicle drives over the scanner, the system acquires automatically a high-resolution image of its undercarriage and recognizes its license plate.

Based on reference images, a powerful algorithm automatically detects any changes or foreign objects hidden under the vehicle and alerts the operator by displaying on the screen the potential areas of threats: weapon, explosive device, drug…

Once the inspection is completed, the operator authorizes or not the vehicle to pass. All data collected during process are stored in a shared database.

TREX-UVSS is the ideal solution to ensure an efficient control of the vehicle’s undercarriage.

Actually, TREX-UVSS is designed to :

  • Acquire automatically a high-resolution image of the vehicle’s undercarriage whatever its length: car, truck, trailer…
  • Scan the vehicle in both directions.
  • Recognize automatically the license plate.
  • Detect automatically any changes or foreign objects hidden in the vehicle undercarriage by comparison with reference images stored in the database.
  • Alert operator in case of any threats detected.
  • Inspect quickly, fully, efficiently and safely for the operator the vehicle’s undercarriage at the entrance of sensitive sites.
  • Export all collected data to an SQL database.
  • Integrate with external host systems and traffic control equipment: video surveillance systems, barriers, road blockers…
  • Be efficient 24/7.
  • Resist to heavy vehicles.
  • Offer a powerful Software Suite with an intuitive graphical user interface.
