    Abstract: Systems and methods are provided for navigating an autonomous vehicle using reinforcement learning techniques. In one implementation, a navigation system for a host vehicle may include at least one processing device programmed to: receive, from a camera, a plurality of images representative of an environment of the host vehicle; analyze the plurality of images to identify a navigational state associated with the host vehicle; provide the navigational state to a trained navigational system; receive, from the trained navigational system, a desired navigational action for execution by the host vehicle in response to the identified navigational state; analyze the desired navigational action relative to one or more predefined navigational constraints; determine an actual navigational action for the host vehicle, wherein the actual navigational action includes at least one modification of the desired navigational action determined based on the one or more predefined navigational constraints; and cause at least one adjustment of a navigational actuator of the host vehicle in response to the determined actual navigational action for the host vehicle.

    Abstract: A driver assistance/control system includes a camera operatively connectable 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.
