Problems solved by technology

[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
In the face of complex road conditions, especially when there are no guide signs or blind roads installed at the intersection, even if the visually impaired have aligned with the pedestrian crosswalk, it is very easy to walk out of the pedestrian crosswalk and walk into the middle of the road with dense traffic, which leads to danger. sex increase

Abstract

The invention discloses a navigation method and apparatus for the blind at a pedestrian crossing, which belong to the technical field of navigation for the blind. The navigation method for the blind at the pedestrian crossing is characterized by comprising the following steps: identifying the pedestrian crossing; determining a horizontal offset and a deviation correction angle of the blind away from the pedestrian crossing, wherein the horizontal offset and the deviation correction angle are determined by acquiring a moving image of a blind navigation walking stick; and performing the navigation according to the horizontal offset and the deviation correction angle. By adopting the navigation method and apparatus for the blind at the pedestrian crossing, the blind can be helped to successfully pass through the pedestrian crossing, and the safety guarantee of the blind can be improved.

Description

technical field [0001] The invention relates to the technical field of navigation for the blind, in particular to a navigation method and device for the blind at pedestrian crossings. 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. In the face of complex road conditions, especially when there are no guide signs or blind roads installed at the intersection, even if the visually impaired have aligned with the pedestrian crosswalk, it is very easy to walk out of the pedestrian crosswalk and walk into the middle of the road with dense traffic, which leads to danger. sex increased. [0003] Therefore, for blind people who need to cross the pedestrian crossing line in the middle of the road, in the absence of blind roads, accurate path planning and navigation are very important. Contents of the invention [0004] In order to solv...
