Abstract

The invention provides an intelligent guiding system based on image recognition and used for the blind, belonging to the technical field of artificial intelligence. According to the invention, a userterminal comprises an information collection module which collects video image data, voice navigation instructions, real-time motion data and real-time position information in front of a person with visual impairment in real time. A cloud server comprises a cloud navigation module for generating a navigation route according to the voice navigation instructions and the real-time position information, and a cloud decision module used for detecting a target object in the advancing direction of the visually-impaired person according to a first target detection model and generating a cloud feedbackinstruction to guide the visually-impaired person to advance in a voice broadcast mode. The user terminal further comprises a local decision module which detects the target object in the advancing direction of the visually-impaired person according to a second target detection model and generates a local feedback instruction to guide the visually-impaired person to advance in a voice broadcast mode when the cloud decision module does not respond in time. According to the invention, various obstacles and traffic lights can be effectively identified, and visually-impaired people can be assistedin accurately perceiving a surrounding environment.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to an image recognition-based intelligent blind guiding system. Background technique [0002] The visually impaired cannot perceive the world through vision, and must rely on touch, smell, and hearing to perceive the space in which they live, which makes it difficult for them to travel and greatly limits their freedom of travel. According to incomplete statistics from the World Blind Union, there were 40 million to 45 million blind people in the world in 2018, and researchers said that by 2050, the number of blind people in the world will double to triple. China is the country with the largest number of blind people in the world, with about 5.5 million blind people. No matter from the perspective of the world or China, the number of blind people is extremely large. At present, the blind travel mainly rely on the help of blind sticks and guide dogs. However, guide d...
