Abstract

A method for calibrating a road monitoring device in which, for a predefined calibration period, the positions of detected objects in relation to the road monitoring device are recorded and an accumulated object residence map is formed therefrom. A world coordinate map of the lanes or lane centers for the monitoring region with their position in a predefined world coordinate system. A position and orientation are determined automatically with a predefined degree of correspondence by computer-based movement and/or rotation of the accumulated object residence map or an object residence map derived from it, in particular a filtered object residence map, and computer-based determination of a respective degree of correspondence to the world coordinate map. The actual position and actual orientation of the sensor are derived from this position, and the position of the objects is calibrated accordingly.
