Abstract: A vehicular vision system includes first and second cameras disposed at a vehicle and having respective overlapping fields of view that include a road surface of a road along which the vehicle is traveling. Image data captured by the cameras is provided to an image processor and is processed to determine relative movement of a road feature present in the captured image data. The determined movement of the road feature relative to the vehicle in first image data captured by the first camera is compared to the determined movement of the road feature relative to the vehicle in second image data captured by the second camera, and at least a rotational offset of the second camera at the vehicle relative to the first camera at the vehicle is determined and the image data are remapped to at least partially accommodate misalignment of the second camera relative to the first camera.
