1. Method for detecting a clear path of travel for a vehicle, the detecting comprising a fusion of a plurality of analyses, the method comprising: monitoring an image from a camera device; analyzing the image through clear path detection analysis to determine a clear path of travel within the image; analyzing an area in front of the vehicle utilizing a topographical variation analysis to determine a flat surface upon which the vehicle can travel, the topographical variation analysis comprising at least one of: utilizing a ground plane estimation analysis to compile a map that describes height variation on a surface in the area in front of the vehicle to determine an elevation contour of a ground plane in front of the vehicle, and utilizing a snow elevation change analysis estimating a transition in height of snow in front of the vehicle; combining the clear path of travel and the determined flat surface to describe an enhanced clear path of travel; and utilizing the enhanced clear path of travel to navigate the vehicle.
