Median value filter is used to eliminate or reduce the noise caused by the outside environment. The edge information of road image is enhanced by Sobel operator. And then based on the Otsu method, an effective algorithm is proposed to binary-code the lane image in order to segment and identify road edge easily. Finally, Hough transformation is used to extract the feature of lane and detect the lane...
Preprocess the lane gray image to obtain binary image by using median filtering, Sobel edge detection operator and image segmentation algorithm based on maximum entropy. Propose an improved Hough transformation algorithm to obtain the feature parameter of the road edge in the binary image. Establish the area of interest (AOI) of the road edge, according to the prediction result of the Kalman filtering;...
