Blind guiding mobile phone and blind guiding method

Abstract

The invention discloses a blind guiding cell phone, which comprises a baseband processing module and a voice output module, a range sensor and a camera shooting module, wherein the range sensor is used to detect barriers in the front and send the detecting results to the baseband processing module, the camera shooting module is used to collect the image data of the barriers in the front and transmit to the baseband processing module, the baseband processing module is used to gain the range information according to the detecting results and conduct the image matching identification for the barriers according to the image data and a local object mold base, and transmit the type and the range information of the barriers which are identified to the voice output module, and the voice output module is used to provide the type and the range information of the barriers to users through the voice way. The blind guiding cell phone and the process of the invention can provide specific information of the barriers for users, which is convenient for the action of users under the condition of paropsia.

Description

technical field [0001] The invention relates to blind-guiding technology, in particular to a blind-guiding method and a blind-guiding mobile phone. Background technique [0002] In real life, blind people need to rely on blind guide devices to assist them in walking when they walk alone. Among them, the simplest and most commonly used device is an ordinary walking stick. By tapping on the ground with a cane, it can help blind people find obstacles around them. Its main disadvantage is that it cannot find obstacles farther away and prominent obstacles in the air. [0003] In order to better help blind people walk, various electronic blind guide devices have appeared on the market, among which, mobile phones or other hand-held devices with blind guide functions are common. This hand-held device with blind-guiding function is usually based on various satellite positioning systems, such as the Global Positioning System (GPS, GlobalPosition System), which determines the current ...

AI Technical Summary

Problems solved by technology

The disadvantage of this blind guide device is that the positioning accuracy is not high, especially it cannot accurately inform the user of the surrounding environment information

At the same time, since this device needs to receive satellite signals for positioning, this device will not work properly when the user is indoors or there are obstacles blocking the GPS signal
