基于分段切换模型的快速车道线检测
FAST LANE LINE DETECTION BASED ON PIECEWISE SWITCHING MODEL
摘要
Abstract
In order to make up for the shortcomings of the single model in lane line detection and improve the real-time and accuracy of the lane line recognition, a highway lane line detection algorithm combining Hough transform and quadratic curve model is proposed.First, the algorithm divides the region of interest.And on the basis of LOG operator for edge detection of the ROI, the Hough transform is performed to detect the straight line.Second, according to the detected line, it further dynamically divides ROI and straight line detection.Finally, the straight line and the quadratic curve are switched to determine the lane line by judging the direction change trend of the two straight segments.Through the experimental test of the actual lane of the freeway, the experimental results show that, the algorithm can accurately detect the lane line, the accuracy and practicality are higher than the contrast algorithm.关键词
