Machine vision cameras catch traffic offenders using stereo software algorithms

Traditional traffic enforcement devices require laser, radar, or inductive loop sensors and a camera to provide documentation of the traffic violation. These systems are limited to vehicle speed measurement, one vehicle at a time.

Because of these limitations, Italian traffic control company Kria (Milan, Italy) developed T-EXSPEED, an automated system that relies on cameras and stereo software algorithms to track and detect traffic violations. T-EXSPEED operates without the use of external sensors and can detect multiple traffic violations such as excessive speed, red light violations, and forbidden left or right turns directly from images taken by industrial cameras that repeat the real-time stereo process 24/7.

The system can measure vehicle speed up to 300 km/h and track vehicles in parallel (up to a three-lane footprint), in both directions. The original T-EXSPEED system is based on three Prosilica GC cameras, from Allied Vision Technologies (Stadtroda, Germany). The newer T-EXSPEED 2 version relies on three Prosilica GB cameras.
