Abstract
The driver assistance system includes a camera operatively connectable to a processor. The driver assistance system is operable while the host vehicle is moving to detect a deviation in vertical contour of a road. A first image frame and a second image frame are captured in the field of view of the camera. Image motion is processed between respective images of the road derived from the first image frame and the second image frame. The vertical contour of the road is estimated using a road surface model of the road and the deviation in the vertical contour is computed from the road surface model.
