摘要
The location of a vanishing point determined by boundaries of a road indicates the direction of the road. The detection of reliable road boundaries is a nontrivial task in most scenes, however. We propose an algorithm that uses hypothesized vanishing points to extract the road boundaries. Based on the direction and strength of edges in an area for a hypothesized vanishing point, a performance measure is computed. This performance measure reflects confidence in the hypothesis that the given vanishing point is the correct vanishing point for the road. The vanishing point for the given image, and the corresponding road boundaries is selected by searching for the maxima of the performance measures. The efficacy of our approach is demonstrated using several real-world road images.
