Intelligent blind guiding system based on mobile terminal and blind guiding method thereof

Abstract

The invention discloses an intelligent blind guiding system based on a mobile terminal and a blind guiding method thereof; the intelligent blind guiding system is characterized by comprising the mobile terminal, and a visual perception unit, an obstacle perception unit and a voice control unit connected with the mobile terminal; the visual perception unit is used for collecting and parsing image information of surrounding environment; the obstacle perception unit uses the supersonic wave technology to detect whether obstacles exist in surrounding environment or not; the information collected by the visual perception unit and obstacle perception unit is sent to the mobile terminal for processing and analysis; processed information is outputted to the voice control unit, and presented for the blind in a voice broadcast mode, thus realizing blind guiding. The intelligent blind guiding system can timely and accurately obtain surrounding environment information, is convenient in usage, and can accurately guide the blind people.

Description

technical field [0001] The invention belongs to the technical field of intelligent equipment, and in particular relates to an intelligent blind guiding system and a blind guiding method based on a mobile phone terminal. Background technique [0002] The World Health Organization estimates that there are 40 million to 45 million visually disabled people in the world, and the number of low vision people is three times that, about 140 million people. There are about 13.5 million people with visually disabled people in my country. As a special group of people, blind people cannot study, work and live like normal people due to their own factors, and even need care from others. [0003] Nowadays, with the rapid development of information technology, smart devices and terminals are becoming more and more mature. With the development of society and the demand of the market, mobile phones for the blind gradually appear in people's field of vision, which can not only make their lives...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, smart glasses for the blind with image recognition and communication have appeared, and blind-guiding canes that use ultrasonic waves to sense obstacles have also appeared. However, these blind-guiding devices have single functions, complex designs, and are not smart enough to Help the blind to obtain the surrounding environmental information in a timely and accurate manner, so that it cannot achieve a good blind guiding function
