基于最优阈值和Hough变换的车道线检测方法

Lane Detection Based on the Optimal Threshold and Hough Transform

针对智能车辆视觉导航系统中的车道保持问题,采用图像处理技术检测结构化道路上的车道线。详细介绍了图像的灰度特征,并在此基础上选取感兴趣的道路区域,通过最优阈值对道路区域进行边缘检测,再结合Hough变换技术检测当前车道线。实验表明用结合最优阈值和Hough变换来检测车道线具有很强的鲁棒性和抗干扰性。

To keep an intelligent vehicle on the lane in the vision-based navigation, an image processing technology is proposed to detect the lane of a structured road. The lane edge is detected through Optimal Threshold, and the current lane is detected in combination with the Hough Transform. Experimental results are also given.
