Problems solved by technology

[0003] The outdoor activities of visually impaired people need to deal with complex and changeable road conditions. The road information obtained by relying on guiding infrastructure and auxiliary equipment is limited. The obstacles on the blind road are unknown and uncertain, and the guiding infrastructure itself is also damaged. Relying on the existing navigation system, it is difficult to provide obstacle avoidance guidance for the outdoor activities of the visually impaired

Abstract

The embodiment of the invention discloses a navigation method and device for the blind and terminal equipment and belongs to the technical field of navigation for the blind. The navigation method for the blind provided by the invention comprises the following steps of: acquiring information of a sidewalk for the blind; judging whether the sidewalk for the blind has an obstacle or not according to the information of the sidewalk for the blind; if so, judging whether the obstacle is a dynamic obstacle or a stationery obstacle; and performing navigation for the blind differently according to the obstacle judging results. According to the navigation method and device for the blind and the terminal equipment provided by the embodiment of the invention, obstacle-avoiding guidance can be better provided for the blind.

Description

technical field [0001] The invention relates to the technical field of navigation for the blind, in particular to a navigation method, device and terminal equipment for the blind. Background technique [0002] Due to lack of vision, the blind (visually impaired) cannot directly observe the surrounding environment, and often have great inconvenience and danger when traveling. Blind people must rely on guiding infrastructure (blind trails, Braille signs) and auxiliary equipment (guide canes, guide dogs, etc.) for outdoor activities. [0003] The outdoor activities of visually impaired people need to deal with complex and changeable road conditions. The road information obtained by relying on guiding infrastructure and auxiliary equipment is limited. The obstacles on the blind road are unknown and uncertain, and the guiding infrastructure itself is also damaged. Relying on the existing navigation system, it is difficult to provide obstacle avoidance guidance for the outdoor ac...
