Development of a Smartphone-based Real Time Outdoor Navigational System for Visually Impaired People

In this paper, we have given a practical solution for solving the problem of visually impaired people using a android based mobile platform. An application is created for detecting obstacles, ups & downs in front of the user. It also detects safe zone in pedestrian lane & gives audio feedback. Using techniques of hough transform and segmentation a real time outdoor navigational system is implemented at the least expenses. It detects line in real time video and make use of OpenCV library.
