    Abstract: A driver assistance/control system includes a camera operatively connectible to a processor mountable in a host vehicle. A vertical deviation in road contour is detected while the host vehicle is moving. First, second and third images of the road are captured from the camera. By matching image points of the road in the first image and corresponding image points of the road in the second image, a first homography is computed which transforms the first image of the road to the second image of the road. A second homography is computed which transforms the second image of the road to the third image of the road. A chained homography is computed by chaining the first and second homographies. By using the chained homography as an initial guess, a third homography is computed which transforms the first image of the road to the third image of the road.

    Abstract: A navigational system for a host vehicle may comprise at least one processor. The processor may be programmed to receive an image representative of an environment of the host vehicle; analyze the image to identify a navigational state associated with the host vehicle; and determine, based on the navigational state, a navigational action for the host vehicle based on a policy that maps possible navigational actions to sensed states. The navigational action may be based on a safety constraint applicable to the navigational state, the safety constraint including a safety distance constraint associated with the host vehicle, wherein the safety distance constraint is based on a determined speed of the host vehicle and a determined speed of a detected target object. The processor may cause an adjustment of a navigational actuator of the host vehicle to implement the determined navigational action.
