Abstract: A method for deriving extrinsic camera parameters of a vehicle camera. Calibration markers are provided on a flat ground surface and the vehicle is driven past the calibration markers. Marker boundaries are detected and matched to stored pre-determined shape parameters and a marker shape is identified. At least one extrinsic parameter of the camera is derived using the tracked positions of identified marker shape in the video sequence captured while vehicle is moving, wherein the extrinsic parameter is selected from mounting positions and a rotation is selected from both horizontal axis and vertical axis of a vehicle coordinate system.

Abstract: A damage recognition assist system of a vehicle, the system includes at least one vehicle camera adapted to provide a stream of camera frames including camera images of the vehicle's surrounding and of areas or parts of the vehicle's chassis; a monitoring unit adapted to detect an imminent interaction of the vehicle with an external object and to identify areas or parts of the vehicle's chassis possibly affected by the detected interaction; a comparison unit adapted to compare recent camera images of the possibly affected areas or parts of the vehicle's chassis with previous camera images of the same areas included in reference camera frames to determine the state and level of damage of the vehicle's chassis due to the detected interaction.
