7 PoliScan speed Measurement Principle Scanning DTU Multi-stage signal processing Scene analysis: Moving objects are tracked, background is discarded Multiple vehicles can be distinguished unambiguously

8 PoliScan speed Detection and Tracking Unit High speed scanning LIDAR No single point/beam measurements Ongoing scene analysis Multi-object, 2D signal processing High measurement accuracy Eye safe class 1 laser Measures distance (time of flight) and angle at each position Tracks multiple moving vehicles, discards background interference Infringing vehicles are reliably detected distance angle 7/15/2013 8
