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.
