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 guide method and a blind guide system. The blind guide method comprises the steps of locating the current position of a blind person; shooting road information of the current position; conducting analysis on the road information of the current position, and informing the blind person of an analysis result in a phonic mode. The blind guide system comprises a location device, a shooting device, a processor and a voice prompter, wherein the location device is used for locating the current position of the blind person; the shooting device is used for shooting the road information of the current position; the processor is used for conducting analysis on the road information of the current position shot by the shooting device and generating the analysis result; the voice prompter announces the analysis result generated by the processor in a phonic mode. By means of the blind guide method and the blind guide system, not only the simple location and direction judgment can be achieved, but also the analysis can be conducted according to the shot road information, and the blind person can be guided when going out in a safer and more effective mode.

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...
