Abstract:
A method of detecting a clear path in a road of travel for a vehicle utilizing a top-down view classification technique. An input image of a scene exterior of the vehicle is captured. The captured input image represents a perspective view of the road of travel. The captured input image is analyzed. A segmented top-down image that includes potential clear path regions and potential non-clear path regions are generated. The segmented top-down image represents a viewing angle perpendicular to a ground plane. The segmented regions of the segmented top-down view are input to a classifier for identifying the clear path regions of travel. The identified clear path regions are utilized for navigating the road of travel.
