Abstract:
A method of calibrating multiple vehicle-based image capture devices of a vehicle. An image is captured by at least one image capture device. A reference object is identified in the captured image. The reference object has known world coordinates. Known features of the vehicle are extracted in the captured image. A relative location and orientation of the vehicle in world coordinates is determined relative to the reference object. Each of the multiple image capture devices is calibrated utilizing intrinsic and extrinsic parameters of the at least one image capture device as a function of the relative location and orientation of the vehicle in world coordinates.
