Embodiment Construction

[0017] as attached figure 1 to attach Figure 4 As shown, the intelligent navigation glasses for the blind of the present invention are composed of a pinhole camera or CCD 1, a distance measuring sensor 2, glasses legs 3, glasses lenses 4, earphones 5, an information processor system 6, and a data line 7.

[0018] When in use, images of obstacles and road conditions during travel can be collected by a pinhole camera or CCD1, and the distance of obstacles and the degree of road conditions are collected by distance sensor 2. The inner side of the spectacle leg 3, the distance measuring sensor is installed behind the spectacle lens 4 and close to the inner side of the other spectacle leg, and the signal line 7 passes through the hole in the spectacle frame and the spectacle leg, and is connected with the information processing after being drawn out at the end of the spectacle leg. System 6 is connected, through the DSP in the information processing system, the obstacle and road ...

Abstract

The invention relates to a pair of intelligent guiding glasses for blind person and belongs to the electronic information field. The invention consists of a needle-camera tube or CCD, a range sensor,a pair of glasses, an earphone, an information processing system, a imaging processing system, an A / D converter, a speech module, a GPS receiving module, a wireless emitting module, a battery and a data wire; wherein, the needle-camera tube or the CCD is arranged in the interior side of two glass legs and are connected with the information processing system through a sensor; the information processing system consists of a DSP image processing module, a wireless receiving module, a GPS receiving module and a speech output module. The intelligent guiding glasses has the advantages of little volume, light weight, reasonable and smart arrangement position of the needle-camera tube or CCD and the range sensor, high efficiency, little electricity consumption, convenient use and strong practicability.

Description

technical field [0001] The present invention relates to electronic information, in particular to an intelligent navigation glasses for the blind, especially an intelligent navigation for the blind that uses a pinhole camera (or CCD) and a distance measuring sensor to obtain information signals and perform voice prompts after microprocessing by an information processing system. Glasses. Background technique [0002] As a special group in society, blind people need more care and care from the society so that they can live better independently. The most essential problem they face in daily life is walking independently. Now when they walk, more blind people What is most interesting is to walk on the side of the road tremblingly with a traditional guide stick, which is difficult to distinguish the relatively high obstacles and ravines ahead; in fact, many institutions have developed some tools to help the blind walk, such as: The advantage of the speaker navigation stick is tha...
