| Abstract(in English) | This paper presents a method for estimating the distance and detecting the position of stairs from images. In our method, we detect candidate regions of stairs in an input image with the histogram of edge. And we extract the region of stairs using invariants by calculating geometrical features of stairs. Then, we extract the lines of pillars and steps with the edge information and Hough transformation in the region. We obtain 3-D vector with direction of step edge and a surface normal of floor from these edge lines. We estimate the distance from the blind to the nearest point of stairs based on projective geometry and vector analysis. |
