In order to maintain the daily life, many information are required. One Of them is, the visual information which is standard for decision making in daily life. Thus visual information is very important and, if unable to obtain correct visual information, Daily life will have very devastating effects.
The biggest inconvenience for the visually impaired is, walking as a normal person, they also need the other information to walk properly, current position, direction and vision are important factors to identify the risk factors.
To suppose solution for this problems many studied are going on in a variety of ways. the aim of this paper to is to develop stereo vision based self locating technology using GPS information, for a position selected by user/candidate.
A stereo vision system is a three dimensional spatial information of surroung environment, in addition the color separation technique is used to separate the different objects, through this technology surrounding object and risk factors can be easily determined.
The most important element of this technology is to identify the location of skyline, which use the matching information extracted from surrounding and in this way the traffic signs can be recognized. This technology can be installed for the visually impaired persons to recognize Braille blocks so that they can follow safe pedestrian path.
These techniques which are based on the information extracted from the environment is used in a system where a comprehensive self reasoning is performed.
