摘要: This paper proposes a real-time system to provide location based guidance and obstacle avoidance of blind persons in indoor environments. The integrates navigation features on visual recognition markers the detection classification possible obstacles front person. uses Microsoft Kinect sensor acquire RGB-D images scene. RGB camera provides input for tracking algorithm which identifies trained set wall-mounted markers. user's pose is estimated combining marker information with GIS data. Depth used classify nearby obstacles. results experimental tests two subjects are presented discussed.
