Intelligent blind guiding system based on blind sidewalk

Abstract

The invention discloses an intelligent blind guiding system based on a blind sidewalk, which comprises the following steps: step 1, a blind sidewalk navigation device performs blind sidewalk positioning and navigation, draws a blind sidewalk route in a blind guiding map, and guides a blind person to correctly find the position of the blind sidewalk through GPS positioning; step 2, a blind sidewalkrecognition device collects the blind sidewalk state information, whether the blind person deviates from the blind sidewalk or not is judged through an image recognition module, and whether an obstacle exists on the blind sidewalk or not is judged through an obstacle recognition module; step 3, an information processing system analyzes and processes the navigation information and the blind sidewalk state information, judges whether the blind person deviates from the blind sidewalk or not and whether the obstacle exists on the blind sidewalk or not, and converts a result into a corresponding voice prompt signal; and step 4, a voice prompt device generates a voice prompt signal and transmits the voice signal to the blind person to guide the blind person to move forward. The blind sidewalk route and state information is converted into the voice information which can be recognized by the blind person, and the blind person can conveniently master the blind sidewalk route and the blind sidewalk state at any time so as to travel safely.

Description

technical field [0001] The invention relates to an intelligent blind guiding system based on a blind path. Background technique [0002] Blind roads are barrier-free facilities in cities. Nowadays, it has become normal to set blind roads on main streets and sidewalks in cities, but the phenomenon of blind road occupation is becoming more and more prominent, making it difficult for blind people to travel. [0003] The traditional method is to improve the tactile pavement bricks. By designing different concave-convex structures such as bar or dot structures to prompt the blind to walk, the blind can identify the tactile path based on the feeling of the feet or the blind stick, but this cannot help the blind to identify obstacles on the tactile path. And blind people need to wear shoes that can sense the ground when traveling, which makes it very inconvenient for blind people to travel. Current plan 1: Improve tactile paving, design tactile paving with different concave-convex...

AI Technical Summary

Problems solved by technology

[0008] 1. In response to the problem of changing the existing tactile pavement bricks and tactile pavement facilities for related scheme 1, as well as the problem of not being able to identify the occupied blind pavement;

[0009] 2. In response to the problem of changing the existing blind road facilities by installing a series of induction, reminder and energy storage devices on the existing blind road facilities in the second related plan, and the problem that the voice prompts are not easy to hear in a noisy environment;

[0010] 3. For related scheme 3, the use of blind road sensing shoes cannot identify damaged blind roads and the problem that blind people can only wear specific blind road sensing shoes when traveling, and the problem of not being able to identify blind roads being occupied
