Abstract
A novel electronic travel aid for the blind based on stereo vision was proposed. The device has the features of road deviation detection, obstacles detection and traffic lights recognition. Road edges extraction is realized by Canny filter and Hough transfer. Road deviation detection is implemented by judging the position and angle of the road edge. Traffic lights recognition is completed using template matching, and obstacles detection is realized using a self-adaptive threshold determination algorithm. The correct recognition rate of traffic lights is 100%. The correct detection rate of road edge is 92% and that of obstacles is 96%.
