Abstract
A device for the identification of vehicles in a road control station by means of image processing of at least one image recorded by a video camera. The vehicles (4, 5), that shall be identified are illuminated by means of an illumination device (12) with light in a pattern, so that a light structure is obtained on the surfaces of the vehicles (4, 5) facing the source of light. Thereby, stereo recordings can be used in the image processing for the determination of the height contour (4, 5) of the vehicles by using the ligth structure of the surfaces of the objects.
