Indoor navigation system based on omni-directional corridorguidelines

Finding way in indoor environments may pose a challenge to people who have some sort of visual loss. This paper describes straight corridor positioning and junction detection algorithms for use in indoor navigation system which is designed for the visually impaired. Also, a model that extracts the edges from the image captured by omni-camera is proposed and the system can direct the visually impaired according to the edge information so that they can move in correct direction and in the middle of the corridor. The proposed navigation system was carried out using omni-camera which can capture images of 360deg view. It has many advantages compared with the conventional camera. Our experiment results show that it works well in corridor environment.
