[0003] So far, the crutch used by most blind people is an ordinary folding stick. The structure of this stick-type crutch in the traditional sense is very simple, and the road condition information it can provide for the blind is extremely limited. Many defects, for example, it cannot allow blind people to accurately and real-time perceive the distance between obstacles in front of them and themselves, nor can they know whether the current road is a blind road

Description
technical field [0001] The invention relates to a crutch, in particular to an intelligent crutch for the blind. Background technique [0002] With the improvement of social living standards, more and more people pay attention to the travel safety of the blind. If the travel safety of so many blind people cannot be effectively guaranteed, it will bring a very serious burden to the family and the society. In the existing street paving, there are lanes for the blind, which are marked with yellow floor tiles, and there are protruding straight stripes and origins on the yellow floor tiles to indicate the route and turn. [0003] So far, the crutch used by most blind people is an ordinary folding stick. The structure of this stick-type crutch in the traditional sense is very simple, and the road condition information it can provide for the blind is extremely limited. Many defects, for example, it cannot allow blind people to accurately and real-time perceive the distance between ...
