Abstract

The method involves monitoring an image from a camera (110), and analyzing the image through clear path detection analysis to determine a clear path of travel within the image. An area in front of a vehicle (100) is analyzed by utilizing a topographical variation analysis to determine a flat surface upon which the vehicle is made to travel. The clear path of travel and determined flat surface are combined to describe an enhanced clear path of travel. The enhanced clear path of travel is utilized to navigate the vehicle. An independent claim is also included for a system for detecting a clear path of travel for a vehicle.
