Obstacles Detecting on Blind Sidewalk System Based on Image Processing Scheme

摘要

A lot of blind sidewalks have been built for the blind people to facilitate their life. In current society, however, it is such a serious phenomenon that the blind sidewalk is occupied by a variety of stuff. With the development of science and technology, some applications served as helpers for the blind people have been developing until recent year. This paper mainly proposes an approach on helping blind people walk on the blind sidewalk. Histogram-based detection methods are used for obstacles and sidewalk recognition in this paper, and methods of image similarity matching are also developed for the detection of obstacles on the blind sidewalk. We processed the images extracted from video streams by the methods presented above and then conducted a couple of experiments to exam the accuracy of this system.
