A machine vision based navigation system for the blind

Blindness aid system has been part of the blind´s life. In this study, we present a new computer vision based blindness navigation system, using robust and stable computer vision technologies to strengthen the weakness of existing electronic intellectual aid device. Our system can offer state information of the road scene, and assists the blind to find out the obstacles and the walkable planar regions, through which the blind can walk independently. The real scene experiments show that our method can provide a robust cognitive result of road scene.
