VIDEO IMAGE TRACK SUPERVISION SYSTEM

摘要

The present invention provides a method for the surveillance of danger zones, especially platforms in stations, that is based on a specific detection geometry dividing the supervision area in pairs of trapezoids, using one trapezoid for detection and the other trapezoid for qualification of detections. The detection geometry is combined with sensitive detection and qualification steps based on video image analysis. A major advantage of the present invention is the continuous scalability of the detection threshold.
