Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to an intelligent navigation and obstacle avoidance travel assistance method and system for the blind. Background technique [0002] The blind are a disadvantaged group in society. At present, guide dogs and guide sticks are mainly used to assist the blind in daily travel. The cost of training guide dogs is high, requires daily consumption, and has a limited lifespan, so it is not possible to widely promote them. The guide stick is composed of a pole and a handle, which give the blind person walking support. Although the blind can find the way with a cane, it is impossible to navigate the direction and route of walking only with a cane or a guide dog. guide the blind. Therefore only by present blind guide tool, blind person can't reach unfamiliar place independently, and its trip relies on the help of relatives and friends to a large extent. The existing navigation c...
