METHOD FOR MEASURING THE HEIGHT PROFILE OF A VEHICLE PASSING ON A ROAD

摘要

The method involves directing monocular camera from a point onto the road with an angle of aperture for capturing a section of the road from above. First image of the passing vehicle is recorded by the camera at a first moment in specific time, and second image of the passing vehicle is recorded by the camera at a second moment in preset time. A movement vector image of the vehicle is generated from an analysis of the optical flow between first and second image, and the height profile of the vehicle is generated from the movement vector image.
