摘要
Abstract
Lane detection is a key technology in the automated vehicle system.There are many methods of lane detection,but the limitation of vehicle system leads to the time complexity of the algorithm is not too high,so it limits the application of many algo?rithms in vehicle embedded devices.In this paper,a fast lane detection method is proposed.Firstly this method extracts the candi?date points in the lane image by projection transformation based on SAT.Then paper uses the Hough transform based on directional filtering to extract the line,it's just a coarse positioning.Finally,paper uses the vanishing point estimation and contrast filter to lo?cate the line.Projection transformation based on SAT can improve the execution efficiency of the algorithm on multi scale.Using a lo?cal projection transformation to each pixel can make the pixel point is not responsible to the brightness of whole image,so it im?proves the robustness of detection and solves the problems in the shadow of lane.Experimental results show that 10 ms per frame in the i7 CPU environment in typical pavement images.关键词
