Intelligent blind guiding method and system

Abstract

The invention discloses an intelligent blind guiding method which comprises the following steps: S1, carrying out voice recognition when voice information is received, judging whether the voice information is preset voice information or not, and if yes, entering a step S2; S2 analyzing the voice information to obtain blind guiding basic information, wherein the blind guiding basic information comprises a starting place, a destination, a travel route and the like; S3, planning a first blind guiding route according to the blind guiding basic information, detection the condition of a front obstacle during advancing, and analyzing the distance, the size, the shape and the like of the obstacle; S4, planning a second blind guiding route according to the distance, the size, the shape and the likeof the obstacle, and carrying out voice broadcast; and S5, obtaining external light brightness information and analyzing the brightness intensity to determine whether to start illumination assistanceor not. Intelligent blind guiding of the blind person is achieved through voice recognition, fault object detection, route planning, voice broadcast, photosensitive illumination and the like, the travel experience of blind people is greatly optimized, and meanwhile family members can conveniently conduct better travel planning for blind people.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an intelligent blind guiding method and system. Background technique [0002] With the rapid development of society and the increasing maturity of science and technology, people have put forward higher requirements for the quality of life. As an inseparable person in this society, blind people have put forward new requirements for helping blind people live and travel better. As a vulnerable group, we not only need a product that allows them to help themselves, but also a product that allows other groups to notice them and provide help. Therefore, providing better resources for the blind and solving the problem of travel difficulties for the blind has become what we need to pay attention to. The current solution for guiding the blind mainly uses auxiliary equipment to provide voice prompts, etc., but this similar solution usually prompts the blind person to see the situatio...
