Road Edges Detection of a Novel Travel Aid for Visual Impaired People

摘要：

　　A road edges detection method of a novel electronic travel aid for the blind was proposed.Road edges extraction was realized by Canny filter and Hough line transfer.Multiple lines detected by Hough transfer were processed into one edge line.Road deviation judgment method was proposed to determine if the user has deviated from the road by judging the position and angle of the edge lines.Experiments showed that the correct extraction rate of road edges was 93%,and the road deviation judgment method was effective and fast.Experiments were done using the consecutive stereo image sequences captured on road.
