Problems solved by technology

[0004] However, the above-mentioned patents only perform simple direction judgment and position positioning on the blind person's location, without making judgment and analysis for complex and changeable road conditions, and still cannot achieve a better blind-guiding effect

Embodiment 1

[0052] refer to figure 2 , Embodiment 1 of the method includes the following process:

[0053] Step 201: locating the current position of the blind person;

[0054] Step 202: photographing the road surface information of the current location;

[0055] Step 203: Compare whether the photographed current location road surface information is consistent with the pre-stored road surface information; if they are consistent, perform step 204; if they are inconsistent, perform step 207;

[0056] Step 204: Determine whether there is an obstacle mark in the pre-stored road surface information, if yes, execute step 205; if not, execute step 206;

[0057]Step 205: voice reminds the blind person to detour;

[0058] Step 206: no reminder or voice reminder to the blind person to move on;

[0059] Step 207: When there is no obstacle sign in the pre-stored road surface information, voice reminds the blind person to make a detour.

[0060] The embodiment refines the basic flow of the afore...

Embodiment 2

[0063] refer to image 3 , the second embodiment of the method includes the following process:

[0064] Step 301: Locate the current position of the blind person;

[0065] Step 302: photographing the road surface information of the current location;

[0066] Step 303: Find the road surface information of the current location in all the pre-stored road surface information;

[0067] Step 304: Compare whether the photographed current location road surface information is consistent with the pre-stored road surface information; if they are consistent, perform step 305; if they are inconsistent, perform step 309;

[0068] Step 305: Determine whether there is an obstacle mark in the pre-stored road surface information, if yes, execute step 306; if not, execute step 308;

[0069] Step 306: voice reminds the blind person to detour;

[0070] Step 307: Calculate the relative position information between the blind person's current position and the obstacle, and remind the blind person...

Embodiment 3

[0076] refer to Figure 4 , the third embodiment of the method includes the following process:

[0077] Step 401: Locating the current location of the blind person;

[0078] Step 402: photographing the road surface information of the current location;

[0079] Step 403: Analyze whether the road surface information at the current location includes traffic-forbidden signal light information; if yes, go to step 404; if not, go to step 405;

[0080] Step 404: voice reminds the blind person to wait or go around;

[0081] Step 405: Remind the blind person to move on without a reminder or with a voice.

[0082] Embodiment 3 is another refinement of the basic embodiment of the method. When the captured road surface information of the current location includes signal light information, it is analyzed whether there is signal light information prohibiting traffic. If there is, the voice reminds the blind person to wait or Detour; if not, then do not remind or voice to remind the blin...

Abstract

The invention provides a blind-guiding method and a blind-guiding system, wherein the blind-guiding method comprises the following steps: locating the current position of the blind person; photographing the road surface information at the current position; analyzing the road surface information at the current position, and notifying the analysis result by voice blind. The blind guiding system includes: a positioning device, which is used to locate the current position of the blind person; a photographing device, which is used to photograph the road surface information of the current position; a processor, which is used to analyze the road surface information of the current position photographed by the photographing device, and Generate an analysis result; the voice prompter, its voice broadcast processor generates the analysis result. The present invention not only simply locates and judges the direction, but also can analyze the captured road surface information, so as to guide the blind people to travel more safely and effectively.

Description

technical field [0001] The invention relates to the field of blind guidance, in particular to a blind guidance method and a blind guidance system. Background technique [0002] Blind people are a special group, and their travel needs special guidance, such as the guidance of a cane for the blind or a guide dog. And now, the travel of the blind has attracted more and more attention from the society. For example, the Beijing subway bus has released the restrictions on guide dogs, allowing blind people to take the guide dog to take the subway bus to facilitate the travel of the blind group. [0003] In addition to guide dogs, technicians have also developed intelligent guidance devices for blind people, such as "A Voice Prompt Device Combination" recorded in Chinese Patent No. 201310598999.X, which uses positioning devices for Detect the user's location, and send out the user's location in voice through the voice device. With this proposal, the effect of detecting position an...
