The system adopts high precision positioning to obtain the positioning data of blind persons, forms pertinent blind guiding information by data processing, conducts broadcasting in the form of speech engine and provides blind persons with omnibearing, accurate and specific blind guiding services in terms of trip.
Description
(1) technical field:
The present invention relates to a kind of intelligent blind guiding system based on hi-Fix, it can provide omnibearing, concrete, accurate guide service for numerous friend's blind persons trip.Belong to the information engineering technical field.
(2) background technology:
Because eyesight lacks, the trip problem is one of major issue of puzzlement blind person or visually impaired people always.How a kind of effective blind-guiding method or system can be provided, and for friend's blind person trip provides accurate, concrete guide, are the focuses of paying close attention in the society all the time, also are the emphasis that the researchist studies.
In traditional blind-guiding method, blind person's trip needs the guide of other people or seeing-eye dog; Perhaps along the sidewalk for visually impaired people or fixedly trace finds familiar position.This traditional method has bigger limitation, when the blind person need go to a unfamiliar place, can't provide effective guiding.
For solving the defective of traditional blind-guiding method, also there are some blind-guiding method or systems to occur recently based on modern information technologies.As based on the blind-guiding method of fixation locus, voice-based blind-guide device or the like.But these methods only can solve the problem of some aspects at present within the specific limits, can not form an effectively whole blind guiding system, for the blind person provides accurate, concrete guide service.And itself also has certain defective and restriction these blind guiding systems.As, along in the blind-guiding method of track, made full use of the effect of sidewalk for visually impaired people and stationary conduit, guide the blind person to arrive at the destination in conjunction with coordinate location method, but this method must have sidewalk for visually impaired people or stationary conduit, can guarantee that the blind person walks on sidewalk for visually impaired people or stationary conduit always, and limitation is very big; Simultaneously, the precision of coordinate location method is not high enough, can't high-precisionly locate, thereby the guide information that provides is accurate inadequately.For another example, in the voice-based blind-guide device invention, proposed to provide for the blind person scheme of guide by voice, but clearly do not propose how to obtain effective guide information and carry out speech play, promptly there is not accurate localization information, can't judge blind person's position accurately, just can't provide accurate guide information yet, accurately guide is not known where to begin.
For solving all deficiencies of existing blind-guiding method, the present invention proposes a kind of comprehensive blind-guiding method and system, for friend's blind person trip provides omnibearing, accurate, concrete guide service based on modern information technologies.In the present invention, adopt the hi-Fix algorithm to obtain blind person's locator data, the electronic chart of combined high precision is determined blind person's exact position, forms accurately guide information pointedly by a series of data processing and judgement, plays by the mode of speech engine.Simultaneously, when the function of apparatus for guiding blind self can not satisfy the demands, also can build the mode of putting through by one, (CallCenter) sends request to guide service centre, guide service centre (CallCenter) adopts the CTI technology, is that the blind person provides pointedly, concrete guide service in the mode of manual service.
(3) summary of the invention:
