Navigation glasses for the blind

Abstract

The invention provides a pair of navigation glasses for the blind. The pair of navigation glasses for the blind solves the problems that existing glasses designed for the blind are few in variety, and it is inconvenient for the blind to go out due to the fact that most glasses are poor in technical content. The pair of navigation glasses for the blind comprises a glasses body. A battery, a pinhole camera, an infrared distance measurement sensor, a GPS receiver, a Bluetooth receiver, an information processor, a voice prompter and a data line interface are installed on the glasses body in an embedded mode. The glasses body is further connected with an external earphone. The pinhole camera, the infrared distance measurement sensor, the GPS receiver and the Bluetooth receiver are all in circuit connection with the information processor, the information processor is in electric control connection with the voice prompter and the earphone, and the battery and the data line interface are in power supply connection with the information processor. The pair of navigation glasses integrates the multiple functions of image pathfinding, distance measurement pathfinding, navigation positioning, path guiding, voice prompting, warning flashing and the like, further has the entertainment function of broadcast listening or music listening, and brings great convenience to the blind.

Description

technical field [0001] The invention belongs to the technical field of spectacles, and relates to a structure of multifunctional spectacles, in particular to navigation spectacles for the blind. Background technique [0002] As a special group in society, blind people need more care and care from society so that they can live better independently.

The most essential problem faced in daily life is autonomous walking. Now when they walk, blind people walk on the side of the road tremblingly with traditional guide sticks. It is difficult for traditional walking sticks to distinguish between relatively high obstacles and ravine

[0003] In fact, many organizations have developed some tools to help blind people walk, such as: a navigation stick with a speaker, which has the advantage of emitting light at night to remind passers-by and drivers, but the disadvantage is that it is fragile and too sensitive; The advantage of blind shoes is that they can be worn on the feet. The disadvantage is that the measurement range is small and there is no voice prompt. At present, there are few types of glasses specially designed for the blind, and most of them have low technical content. It is very inconvenient for them to go out
