Method and system for optimizing guide blind monitoring by real-time obstacle avoidance in actual traffic environment

Abstract

The invention discloses a method and a system for optimizing guide blind monitoring by real-time obstacle avoidance in actual traffic environment. The method comprises the following steps of an audioacquisition and analysis, route planning and design, real-time navigation information determination, timely navigation broadcasting and the like. The system comprises a storage module, an audio acquisition module, an audio data processing module, a positioning device module, a communication module, a route design determining algorithm module, a real-time navigation information determination moduleand an information transmission broadcasting module. The method and the system are stable and reliable, good in anti-interference performance and wide in application range, can guide a blind person to travel in a complicated environment conveniently and timely, and has the advantages that the system is high in intelligence degree, the method is advanced and scientific, a travelling route is safeand accurate and the like; the action freedom of the blind person is greatly improved; the method and the system have practicability and realizability and have high practical value and wide application prospect.

Description

technical field

[0001] The invention relates to the technical field of intelligent control, in particular to a real-time obstacle avoidance optimization blind guide monitoring method and system in an actual traffic environment. 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 ex...
