Abstract
A method for measuring a height profile of a vehicle passing on a road, said method comprising the following steps: directing a monocular camera from a point above the road onto the road with an angle of aperture that captures a section of the road from above, recording at least a first image of the passing vehicle by the camera at a first moment in time, recording at least a second image of the passing vehicle by the camera at a second moment in time, generating a movement vector image of the vehicle from an analysis of the optical flow between the first and the second image, and creating the height profile of the vehicle from the movement vector image.
