Blind aid system based on infrared sensing geometrical characteristic recognition

Abstract

The invention discloses a blind aid system based on infrared sensing geometrical characteristic recognition, comprising a trolley body, a singlechip, an infrared sensor module, a voice prompt module, a power module and a manual control module, wherein the infrared sensor module is used for detecting the distance between the trolley bottom and the ground, distinguishing a striped go-ahead blind sidewalk and a dot-shaped prompt blind sidewalk according to the compared feedback information of an obtained result and transmitting the result to the singlechip; the singlechip is used for processing the blind sidewalk surface geometrical characteristic information detected by the sensor module so as to recognize the prompt blind sidewalk and the go-ahead blind sidewalk, and then dynamically adjusting the motion state of the trolley according to the recognized prompt blind sidewalk and go-ahead blind sidewalk result; the voice prompt module is used for carrying out voice prompt on the condition of the trolley keeping moving straight or reaching to the prompt blind sidewalk; and the manual control module is used for manually controlling the motion state of the trolley. The invention can better provide convenience for the disabled, such as the blind, and the like, thereby improving the life quality of the disabled.

Description

technical field [0001] The invention relates to an auxiliary device for the disabled, in particular to a blind guide system based on infrared sensing geometric feature recognition. Background technique [0002] In daily life, blind people are a group of disabled people who are inconvenient to travel. They cannot recognize directions, nor can they accept the guidance of optical traffic devices such as traffic lights. In today's increasingly urbanized society, their safe and convenient travel is particularly important. With positive psychology gaining prominence, the well-being of people with disabilities deserves attention. [0003] The blind road is the basic public facility of the city. Blind roads can be divided into two categories according to their functions: advancing blind roads and prompting blind roads. The walking path for the blind is in the shape of strips, each of which is 5mm above the ground, which can make the blind stick and the soles of the feet feel, an...
