A fast lane marking recognition algorithm based on edge projection is proposed, which can be used in lane marking recognition and lane tracking. Firstly, the vanishing point in the region of interest is detected based on voting mechanism, object search area is defined and lane feature points are extracted from edge detection information. Then these feature points are projected along gradient direction and counted, with two points on the lane acquired and lane markings detected by confidence judgment. Finally, strip-shaped region is defined and lane tracking is achieved. With TMS320DM6437 as hardware platform, and real-time simulation and debugging program under CCS integrated environment, a real vehicle test is conducted. The results show that the proposed algorithm running on DSP platform has good real-time performance, robustness and accuracy, with satisfactory lane marking recognition and lane tracking effects under complicated environments with shadows, vehicle occlusion, rain and fog.
