Abstract:
A method of calibrating a vehicular camera includes disposing a camera at a vehicle, moving the vehicle along an arbitrary path, capturing image data with the camera, and processing, via a processor, image data captured by the camera. Responsive to tracking a determined feature across multiple frames of captured image data during movement of the vehicle along the arbitrary path, and responsive to received vehicle data representative of the movement of the vehicle along the arbitrary path, misalignment of the camera is determined. The determined camera misalignment is corrected (i) without use of a target in the field of view of the camera as the vehicle moves along the arbitrary path and (ii) without processing of image data captured by the camera that is representative of a target in the field of view of the camera as the vehicle moves along the arbitrary path.
