Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, a two-dimensional tactile path of this embodiment, the two-dimensional tactile path 100 is formed by a combination of different types of tactile path bricks, wherein each type of tactile path brick is a brick form with multi-convex parallel distribution commonly used at present, It specifically includes Type I tactile bricks 300 with surface convex strips, Type II tactile bricks 400 and coded tactile bricks 500, wherein Type I tactile bricks 300 and Type II tactile bricks 400 are both single-color tactile bricks, and the colors of the two are different; Convex strips of different colors are provided on the surface of the tactile paving brick 500; Type I tactile paving bricks 300 and Type II tactile paving bricks 400 are alternately laid along the length direction of the blind pavement to form a two-dimensional traveling blind pavement; The coded tactile bricks 500 of the positions are connected by a two-dimensional traveling tac...

Embodiment 2

[0041] The positioning and navigation system for the blind based on the two-dimensional blind path of this embodiment includes the two-dimensional blind path 100 described in the above embodiment, and the video unit 200, wherein the two-dimensional blind path 100 is formed by combining different types of blind path bricks, specifically as implemented As an example, which will not be repeated here, the video unit 200 is used to collect images of the two-dimensional blind road 100, and obtain corresponding position information and moving distance information through identification and calculation.

[0042] In this embodiment, the video unit 200 includes a camera 201, a communication control module 202 and a voice module 203. The image of the two-dimensional blind road 100 is obtained by the camera 201, and the communication control module 202 performs identification, data and transmission, and the voice module 203 uses the position and distance The information is communicated to ...

Abstract

The invention discloses a two-dimensional blind sidewalk, a blind person positioning and navigation system based on the two-dimensional blind sidewalk and a navigation method of the blind person positioning and navigation system, and belongs to the field of positioning and navigation. The two-dimensional blind sidewalk comprises I-class blind sidewalk bricks, II-class blind sidewalk bricks and coding blind sidewalk bricks, wherein the I-class blind sidewalk bricks, the II-class blind sidewalk bricks and the coding blind sidewalk bricks are provided with convex strips on the surfaces; the I-class blind sidewalk bricks and the II-class blind sidewalk bricks are single-color blind sidewalk bricks with different colors; convex strips with different colors are arranged on the surfaces of the coded blind sidewalk bricks; the I-type blind sidewalk bricks and the II-type blind sidewalk bricks are alternately laid in the length direction of the blind sidewalk to form a two-dimensional advancing blind sidewalk, the coding blind sidewalk bricks are laid in corresponding specific positions in the length direction of the blind sidewalk, and the coding blind sidewalk bricks in different positions are connected through the two-dimensional advancing blind sidewalk. According to the invention, the defects of poor practicability and high cost of the blind navigation technology in the prior art are overcome, the normal blind sidewalk bricks meeting the standard are directly utilized for design optimization, positioning navigation can be realized, the production cost is effectively reduced, the feasibility is reliable, and the method has full popularization significance.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, and more specifically, relates to a two-dimensional blind path and a positioning and navigation system for blind people based on the two-dimensional blind path and a navigation method thereof. Background technique [0002] The development of positioning and navigation technology has greatly changed people's travel experience, but the blind travel in the city still needs to rely on feeling the convex strips on the blind road to ensure the direction of walking, feeling the bumps on the blind road to determine whether there are intersections or obstacles ahead Or a fork in the road, completely unable to appreciate the convenience that modern navigation technology brings to people. How to realize the effective navigation assistance for the blind gradually attracts people's attention. [0003] At present, many technologies have been disclosed to try to change this situation. For ex...
