Blind guiding system based on electronic blind crutch and non-concave-convex blind track

Abstract

The invention discloses a blind guiding system based on an electronic blind crutch and a non-concave-convex blind track. The blind guiding system comprises the electronic blind crutch and the non-concave-convex blind track arranged on a sidewalk, wherein the electronic blind crutch comprises a camera shooting unit, a processing unit and a prompt unit; the non-concave-convex surface of the non-concave-convex blind track is provided with a blind guiding mark comprising bar patterns and dot patterns; the camera shooting unit is used for acquiring the blind guiding mark; the processing unit is used for generating blind guiding prompt information used for guiding blind people by analyzing the blind guiding mark; the prompt unit is used for realizing blinding guiding by voice frequency prompt or vibration prompt. According to the blind guiding system, the electronic blind crutch provided with a machine vision system is used for replacing the existing blind foot touch system and recognizing the blind track, so that the concave-convex part of the blind track can be removed, and diversified blind guiding services can be provided.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a blind guiding system based on an electronic blind stick and a non-concave-convex blind path. Background technique [0002] The blind road is a public road infrastructure to solve the travel problem of the blind. It guides the blind through the blind stick and the touch of the soles of the feet. According to the People's Republic of China industry standard JGJ-50-2001 "Code for Barrier-free Design of Urban Roads and Buildings", the blind road that guides the blind to walk forward should be a strip-shaped walking blind road ( figure 1 (a)), at the starting point, end point and turning point of the blind road, a dot-shaped warning road for the blind should be set up ( figure 1 (b)). The recommended color for blind walkways is medium yellow. [0003] Existing blind roads provide convenience for the blind to travel, but also have the following disadvantages: 1) ...

AI Technical Summary

Problems solved by technology

[0003] Existing blind roads provide convenience for the blind to travel, but also have the following disadvantages: 1) The service objects of the blind roads are limited, only helpful to the blind, but bring negative impacts to other road users

2) In order to truly achieve the purpose of effectively helping the blind, it is required that the entire section of the blind road should not be interrupted, otherwise it will not only fail to help the blind, but may bring danger

In the current reality, the interruption of the blind road is difficult to avoid, for example, the blind road is damaged, blocked, temporarily occupied, and the pedestrian crossing crossing the road does not have a blind road, etc.

3) The construction of the existing blind road is troublesome

Due to the way of embedding the existing floor tiles, 90-degree turns are usually used to avoid obstacles, and some places are even repaired into a zigzag shape, which brings great inconvenience to the blind.

In addition, the blind road is uneven, easy to damage, and difficult to repair in time

4) There are only two types of blind roads, indicating that blind roads include a wide range of meanings (such as turning, downhill, bus stops, etc.) In fact, it is difficult for blind people to judge

Therefore, from the actual effect, the utilization rate of the existing blind road is very low, not only cannot provide effective help to the blind, but also affects the travel of other groups of people
