Given an image of the road that is not clear. The computer must determine where the road in that image. Here this road detection process is mainly divided into two steps. 1) Detection of the vanishing point associated with the road. 2) Segmentation of the road area. A new method for detecting the vanishing point based on twice Hough transform is presented in this paper. The first Hough transform is used to detect the straight lines in the image. Then it uses a coordinate transform to translate the points in a circle to points in a line. Finally a Hough transform is used again for the detection of a line. From the parameters of the line the position of the vanishing point can be calculated. Then OCR based road segmentation is used to find the two most dominant edges of the road based on the detected vanishing point.
