World Health Organization (WHO) has estimated that there are about 45 million visually handicapped people worldwide. These visually impaired people experience serious difficulties in leading an independent life due to reduced perception of the environment. Most of them confront serious difficulties in mobility and navigation, when they find themselves in new, unknown environment. In this paper, we have developed a technique that automatically detects obstacles and help the blind user in navigation. In this paper, we have discussed in detail all the design issues involved in the development of stereo vision based navigation technique for the blind people. The results of the technique are presented and they show that the technique can detect obstacles with sufficient accuracy and can easily help a blind user in navigation.

Keywords: Automatically detects obstacles, Disparity map, Stereo vision, segmentation
