Abstract
This paper presents a high accuracy, far range stereovision approach for driving environment perception based on 3D lane and obstacle detection. Stereovision allows the elimination of the common assumptions used in most monocular systems: flat road, constant pitch angle or absence of roll angle. The lane detection method is based on clothoidal 3D lane model. The detected lane parameters are the vertical and horizontal curvatures, the lane width and the roll angle. The detected lane profile is used for road obstacle features separation. Based on a vicinity criteria the over road 3D points are grouped and tracked over frames. The system detects and classifies the meaningful obstacles in terms of 3D position, size and speed.
