A method of automatically and accurately detecting regions of sidewalks and recognizing their attributes is useful for assisting pedestrians. There are several types of sidewalk borders: steps, white lines, guardrails, walls, plants, and ditches, for example. However we can assume that the structure of an environment along some direction is uniform for several meters regardless of the components of the environment. Therefore, we present a method to detect the direction and extract borders of sidewalks by using this assumption. We mount stereo vision camera on low-speed electric buggy and generate gray scale images and disparity images. In this paper we show an algorithm to detect candidates of a borderline from these images by using affine transformation and active contour models.
