Abstract :
This paper propose a road-boundary detecting algorithm by using similarity image which is formed by ladar points. The algorithm transforms 3D point cloud to 2D similarity image to compute the similarity among neighbor points and then uses iterative threshold to segment traversable area. Road-boundary is detected by Canny operator and Hough transform at last. Experiments testify this method can detect road-boundary in structured environment.
