Embodiment Construction

[0069] In terms of identification: the blind person puts the mobile phone in his pocket or holds it in his hand, and the acceleration sensor of the mobile phone records the three-axis acceleration sequence collected by the blind person, and obtains the eigenvalues ​​of the sequence as the relevant behavioral characteristics of the blind person. The data is trained and categorized to identify blind people.

[0070] In terms of navigation and positioning: when the blind person is indoors, because the indoor GPS signal cannot be received well, the acceleration sensor and gyroscope of the mobile phone can assist the blind person in path navigation; outdoors, GPS navigation is used.

[0071] specific plan:

[0072] First, train the smart phone of the blind person so that the mobile phone of the blind person can recognize the identity of the owner. Sudden changes, after the mobile phone falls to the ground, the mobile phone is in a static state at this time, and the data of the bui...

Abstract

The invention discloses a blind person identification and guiding type blind guide method based on a smart phone. Firstly, the smart phone of a blind person is trained, so that the smart phone of theblind person can identify the identity of the owner; the mobile phone is in a static state after being dropped on the ground, the data of a built-in acceleration sensor are invariable at this time, sothat it is judged that the mobile phone is dropped on the ground, the mobile phone emits the sound of dripping water at this time, and thus the blind person can find the mobile phone along with the sound of dripping water. If the mobile phone is stolen by the others, the data change of the built-in acceleration sensor is abnormal, alarm information is automatically sent to a guardian to remind the guardian that the mobile phone is deviated. Secondly, the walking path of the blind person is navigated. At first, the guardian guides the blind person to walk the common paths for one time and record the path. The blind person identification and identification can be realized by the universal mobile phone, so that the practicability is high, and the cost is low.

Description

technical field [0001] The invention belongs to the field of personal safety, and in particular relates to a smart phone-based blind person identification and guided blind-guiding method. Background technique [0002] According to a survey on December 12, 2014, according to the assessment of the International Guide Dog Federation, the ideal ratio of visually impaired people to guide dogs is 100:1. But at present, there are about 17.31 million visually impaired people in the country, and there are only about 70 guide dogs. And the training cost of a guide dog is between 120,000 and 150,000 yuan. In real life, the public space faced by blind people and guide dogs is also greatly restricted. Above-mentioned various factors cause guide dog and can not obtain great popularization. To a certain extent, the emergence of guide dogs has not brought good news to most blind people. [0003] With the continuous development of science and technology, smartphones are no longer limited ...
