Abstract Estimating the depth of the road scene is a key step for intelligent transportation and robot navigation. This paper presents a depth estimation algorithm for single static road image. The algorithm obtains a series of closed areas of the image bede on the edge growing segmentation algorithm firstly; then we compute the statistic characteristics of each region, including color, area, position, straight lines, vertical lines, and parallel lines. Based on these characteristics, the road vanishing point was further estimated, and the sky, road and vertical regions are estimated. Finally, the depth of the road image is estimated by using vanishing point and the statistic characteristics. Experimental results show that the proposed algorithm can effectively estimate the road vanishing point, as well as the road depth information.
