Abstract: In order to solve the problem of lane line detection in complex weather environment on expressway and urban roads, a lane line detection method in complex lighting environment is proposed. This method can better extract the lane line on the road by automatically adjusting the contrast feature of the image in complex lighting environment, and realize the lane line detection in dark and fog environment. Experiments show that the lane line detection and recognition rate of this method is 96.7% in dark environment and 95.2% in fog environment. It has good robustness, accuracy and real-time performance.
