Dual Objective Based Navigation Assistance to the Blind and Visually Impaired
The visually impaired and the blind lead a challenging life. ETA’s play a vital role in their navigation .In this paper, canny edge detection, morphological operations and Bounding Box are performed for obstacle detection technique. Later depth map creation process is done. The deviation of estimated Depth map with the reference depth map can be used to get the spatial information of the environment which can be given to the visually impaired. This paper provides outdoor(i.e. by GPS modem) as well as indoor(by Machine Vision) navigation assistance by two objectives such as sound as well as voice and can detect any number of obstacles. Indoor navigation is done using Image Processing methodology and Outdoor navigation is done through the use of GPS modem.
