Method for measurement of speed and assigning measured speed to car, involves fading marking in holder on car when car passes monitoring region, where marking represents measurement data of speed measured from car

摘要

The method involves aligning a sensor and a video camera (3) such that a sensor region and an object region are partially overlapped to form a common monitoring region (5). A relative position is established between a sensor coordinate system and a camera coordinate system. Position of a car is determined from a recorded measurement data of speed of the car, and checked for correlation with the measurement data of the sensor. A marking is faded in a holder on a car when the car passes the monitoring region, where the marking represents measurement data of the speed measured from the car.
