Problems solved by technology

In recent years, professors Tadyoshi Shioyama and Mohammad Uddin of Kyoto University of Technology recently published a paper in the British "Quantitative Technology" magazine, providing a kind of "electronic eye", using a micro-camera and a software analysis device, the camera first detects the eyes of the blind. Take pictures on the road, convert the white stripes on the zebra crossing into a grayscale image and feed it back to the computer device, and the computer performs vector analysis on these stripes, so as to judge how wide the crosswalk is and how far away the blind person is, and can also judge and ensure that the blind person walks on the zebra crossing However, this device is complex, difficult to implement and expensive

Embodiment Construction

[0024] Such as figure 1 The direction guiding device provided by the present invention includes an electronic compass 1, a comparator 2 and an alarm device 4 electrically connected sequentially from input to output, and also includes a specified walking direction memory 3 connected to the other input end of the comparator.

[0025] A simple direction blind guide device, the specific structure is as follows figure 2 , including an electronic compass 1, a single-chip microcomputer 5 and an alarm device 4 electrically connected sequentially from input to output, and also includes a button 6 connected to the other input end of the single-chip microcomputer 5.

[0026] When blind friends need to walk in the specified direction, the first step is to face the simple direction guide device in the specified direction, press button 6, and when you hear a "beep", the setting is completed; when walking, once the difference between the direction and the specified direction exceeds the lim...

Abstract

A device for guiding blind person to walk on right direction consists of electronic compass connected in sequence from input to output, comparator, alarm unit and assigned walk direction storage connected to another end of comparator for guiding blind person to walk along right direction. Its guiding method is also disclosed.

Description

technical field [0001] The invention relates to direction recognition recording and intelligent blind-guiding technology, in particular to a direction-guiding method and a device thereof, in particular to a blind-guiding method and a device for determining a direction when crossing a road. Background technique [0002] The applicant of the present invention has previously applied for a Chinese invention patent "an automatic blind-guiding method using positioning technology". The remote server end automatically selects the route and controls the blind person to walk along the selected route through wireless communication. It is necessary to ensure that the blind person travels in the specified direction. , through continuous real-time comparison on the server side, it needs to consume a lot of system resources, so that the system is overburdened and it is difficult to realize the system. [0003] In addition, due to lack or loss of vision, the problem of crossing the road has...
