Automatic Train Undercarriage Inspection System - Embedded Dual View

The Automatic Train Undercarriage Inspection Systems does as the name suggests; automatically inspects the undercarriage of a train’s rail cars. The system is embedded between the rail tracks to allow trains to pass over either a dual- or single-view scanner so that the undercarriage of the individual rail cars is captured. Trains pass over the environmentally-sealed scanner while Gatekeeper’s system scans and compiles one or two (depending on scanner type selected) high-resolution image(s) of the train’s rail car undercarriage to create individual undercarriage digital “fingerprint(s)”. An overview image of each rail car is displayed on a high-resolution monitor along with the resulting scans of the rail car undercarriage. After each rail car has cleared the scanner, it takes between 2 and 3 seconds for Gatekeeper’s Automatic Foreign Object Detection [AFOD] software to automatically compare the newly scanned rail car image to a “safe” rail car image stored in the system database. The system then immediately identifies any foreign object(s) or modification(s) to the undercarriage by

circling them with a red ring (see below) AND activating an audio and/or visual alarm. Gatekeeper’s systems compile two high resolution digital images of a vehicle under carriage and create a virtual “finger print” of the vehicle. Two independent views are necessary to provide the maximum amount of visual information to permit automatic identification and automatic searching. The two views or virtual 3D image makes it more difficult to hide objects, explosives etc on top of an axel or cross beam under a vehicle.

Gatekeeper’s technology uses Area Scan Image Processing technology which allows vehicle images to be normalized regardless of the speed of the vehicle as it crosses the scanning platform. Image capture and processing technologies such as recorded video streams, or line scanning processing are not capable of automatic identification and searching because they require the human operator to view/compare the images and decide if there is any object or modifications that could pose a threat. Live/recorded video and line scanning systems have been proven to be unreliable as an inspection

technology due to poor performance and that they rely heavily on human knowledge, attention span and intervention.

The system can be integrated with tracking technologies such as automatic container number readers (ACNR) & RFID readers.
The standard features as the ability to identify each rail car configuration and size, number of carriages in a train, date and time of the arrival of individual rail cars over the scanner, activity reports and in addition are network enabled requiring only to connect the systems to a common network for remote monitoring or operation.

Applications: Quick and easy to install, the solution for: checkpoints/installations where roads cannot be dug up; events that require a higher level of security; and situations where mobility is required or checkpoints occasionally need to be moved. Why Matrix Security? - Matrix Security manufactures the only fully automatic under vehicle inspection system in the world. - Matrix Security products will give you peace of mind with automatic and highly effective systems that take a lot of the burden off security personnel by making the search process efficient, thorough and easy. - Other obsolete technologies, like video streaming or line scanning, have been proven to be unreliable as an inspection technology due to poor performance and the fact that they rely on the human operator to identify the vehicle and try to find threatening anomalies by looking at running video pictures or poor quality fixed pictures. - Global Reach Service: Matrix Security’s technical support staff can directly service any of its systems 24/7 via broadband Internet access to assist the operator, download software upgrades, run system checks and assist with database management. - Matrix Security’s highly regarded security systems currently help safeguard critical infrastructure such as: royal palaces, embassies, petroleum facilities, nuclear stations and 5-star hotels (just to name a few). - Tested, approved and used by the U.S. Military, Matrix Security’s rugged and reliable systems operate in extreme environments from the harsh cold of Russia to the heat and humidity of the Middle East. Components: The components of the Under Vehicle Inspection System (AUVIS): Mobile platform, dual view scanning system (includes AUVIS image stitching software and automatic change detection software), automatic change detection software, database (includes Watch List for wanted vehicles, Vehicle Verification vs. License Plate, etc.), embedded networking capability, integrated devices (cameras, traffic light, etc.), and 19" daylight readable, LED back lit, touch screen. System Integration & Additional Capabilities: The system can be integrated with weigh-in-motion scales, GatePost biometric systems (fingerprint, etc.), facial recognition, license plate reader, RFID identifier, Smart Card reader, barriers (road blockers, cats claw, bollards or similar) and many other entry control point technologies.
