Lane Extraction Method Based on Vehicle Average Trajectory

On account of the problem that noise points are various and the background is difficult to be extracted in the videos,the lane extraction method based on average vehicle trajectory is proposed.Vehicle positions are acquired in each frame by tracking and the center points of these positions is fit into an average trajectory.One suitable frame is selected from video frames as background and morphologic processing is done so as to eliminate the influential noise points such as the sky or scenery on both sides,and the binary background is obtained by further processing.The lane is extracted by matching the average trajectory with the binary background.Experimental results show that this method can apply to varieties of roads,and it has high success rate and great flexibility and adaptability.
