摘　　要：车道偏离系统是一种安全辅助驾驶系统,针对传统车道偏离预警系统实时性不足,设计了基于改进Sobel算法和Hough变换识别车道线的实时车道偏离预警系统。系统将摄像机采集的道路图像经过改进Sobel算法处理,能更快得到车道线边缘像素信息,再应用Hough变换连接有效边缘像素确定车道线位置,最后通过与预警决策模块的匹配度实现车道偏离的预警判定。经测试系统性能良好。The lane departure system is a safe assisted driving system.Aiming at the shortage of real-time performance of the traditional lane deviation warning system,a real-time lane deviation warning system based on improved Sobel algorithm and Hough transform to identify lane lines is designed.The road image captured by the camera is processed by the improved Sobel algorithm,and the pixel information of the lane line edge can be obtained faster.Then the Hough transform is used to connect the effective edge pixels to determine the lane line position.Finally,the lane deviation warning and determination are realized by the matching degree with the early warning decision module.System test performance is good.
