Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0041] The present invention divides various types of obstacles into two types, namely concave obstacles and convex obstacles, wherein the concave obstacles include open areas (no obstacles) and obstacles that can absorb or transmit detection signals For example, taking the detection signal as an example of infrared rays, black substances can absorb infrared rays, and transparent objects and hollow objects can transmit infrared rays; the convex obstacles refer to objects that can reflect incident signals. Wherein, the concave or convex obstacles respectively include various types of obstacles, for example, the convex obstacles include walls, vehicles, people and other types.

[0042] The structure of the blind guide unit in the blind guide mobile phone of the embodiment of the present invention is as follows: figure 1 shown, including:

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 ...
