Active Guide System for The Blind Based on The Internet of Things and Collaborative Perception

Nowadays, the number of visually impaired people is increasing day by day. On average, one in every 100 people is blind. At the same time, due to the imperfect establishment of social barrier-free facilities, it is very difficult for the blind travelling, which seriously affects the degree of social participation of the blind. This paper introduces a blind guide method based on the Internet of Things and collaborative perception. Coordinate through the long-distance of digital map (eg. Google Maps) and the local navigation mode of the blind guide device to realize an active guide system for the blind. This method can effectively assist the blind to cope with the complex traffic environment and thus perceive the world.
