Blind People Guidance System using Stereo Camera

Blind people need a tool for navigation while walking in an unknown or unfamiliar place. Generally, a stick is one of the solutions to guide them passing the walking path. Their movement is slow because they have to map with a stick, in which the radius of the map is only along to the stick. Another problem comes if there are objects that do not touch the ground, such as railroad crossing gate which cannot be detected by a simple stick. So as to solve this limitation, in this paper, we propose a stereo camera based assistive-system which can detect objects and/or obstacles around the blind people. The ZED Stereo Camera and Computer is used and can detected the distance of obstacles around the system and will be informed to the blind-user via stereo sounds. By this approach, we expected that the blind people can walk faster. From the experimental results, this system works well when used by the blind people. In the end of experiment, the system could achieve 83.16% in accuracy and able to guide blind people to find the walking path confidently.
