Fig. 2 is refer to, Fig. 2 is a kind of flow chart of braille reading method provided in an embodiment of the present invention, methods described tool
Body comprises the following steps：
Step S110：The corresponding reading code of braille file read is put in point-of-reading device identification.
When blind person is carrying out Braille reading, some readings can be carried out on books for the blind by point-of-reading device, so as to incite somebody to action
Braille is played back by audio frequency apparatus with speech form, then blind person can listen the content for getting braille.It can enter first
Printing has a reading code on the braille file that row point is read, and the point reading code that printed on braille file can be identified for point-of-reading device.
Wherein, point reading code can use OID (Optical Identify Digital) hidden code, and point-of-reading device can be
It is a kind of to recognize the talking pen of OID codings.OID codings are that a kind of two-dimentional relation distinguishes coding, pass through the various combination of coding
The different content of identification, and the actual size of these codings is very small, and each point generally corresponds to 5% net of 175 lines/inch
The size of point, the mode that may then pass through common four-colors offset printing is printed on braille paper, and the information to books is not resulted in
Any influence, but visually can not clearly differentiate.
Point-of-reading device obtains the image information for putting the braille file read first, then recognizes corresponding with described image information
Point reading code.Specifically, point-of-reading device can put the contents such as any word, picture, numeral that reading is imprinted on paper, substantially be to distinguish
Include optical camera, image decoding circuit, the audio based on MP3 technologies inside contained various information, point-of-reading device
Decoding circuit, memory, power supply and pronunciation equipment etc..In the present embodiment, the braille file of reading is put in optical camera acquisition
Image information, then identifies the two dimension being printed on braille file or on other braille media corresponding with the image information
Concealed code, that is, put reading code, code value identified by image decoding circuit, and code value is sent to based on MP3 skills by communication interface
The audio decoding circuit of art, the decoding circuit will be stored in corresponding voice document in memory according to code value and pass through pronunciation equipment
Send, power supply is that whole point-of-reading device is powered.The point-of-reading device is mainly using MP3 technologies synthesis voice, using by a large amount of voices
File is packaged into the voice document packaging technique of a file, is set up on packaging file and indexes letter correspondingly with point reading code
Breath, so as to effectively increase the speed from optical camera induction point reading code to pronunciation, shortens the time.Certainly, may be used also
With the embedded AES in program, the voice document after packing is encrypted, to realize the protection to voice document.
As a kind of mode, wireless module can be set on point-of-reading device, for terminal device wireless connection, terminal
Equipment is provided with the APP for being used for managing the point-of-reading device, and user can increase, delete, changing, making an inventory of the study of read apparatus itself on APP
Resource etc., and user can also on the APP on-line purchase education resource, certain education resource is to own in braille file
, the education resource is got up with point reading code and pronunciation one-to-one corresponding, you can carrying out sending corresponding audio content when point is read.
Furthermore it is possible to described corresponding reading code of braille file be encoded using pre-arranged code rule, then by it
Point reading code after coding is printed on braille file, refer to Fig. 3, and Fig. 3 is a kind of reading code provided in an embodiment of the present invention
The schematic diagram of coding rule, the coding of point reading code represents that each N*N dot matrix includes 2N-1 positioning with N*N dot matrix
Point, there is (N-1) * (N-1) individual data point, and each data point can represent 4 numerical value：0,1,2,3.The coordinate of anchor point is：The
A line (whole points remove the 3rd point)：(X1,Y1),(X2,Y1),(X4,Y1),…,(XN,Y1)；Inclined shaft：(X2,Y2),
(X3,Y3),…,(XN,YN)；The lower left corner：(X1,YN).In anchor point, the bottom right of the stain of (X [N-1], Y [N-1]) in region
Angle, the stains of other anchor points all hearts in the zone.
Fig. 4 is refer to, because the anchor point of (X [N-1], Y [N-1]) is in privileged site, according to it may determine that going out a little
4 in battle array size, such as figure multiply 4 dot matrix, and 6 anchor points for multiplying 6 dot matrix are illustrated.There is anchor point on four angles, can be effective
The detection and error checking of point-of-reading device are improved, and anchor point is easy to detect, anti-error ability is strong.
After better reading code is encoded by above-mentioned coding rule, a reading code is printed on braille file, reads to fill by
Put a reading braille file, you can identify the relevant information of a reading code, it is 00,000,001 0,133 0211 for example to put reading code, wherein
First eight bits representing pages information, can correspond to out certain one page of certain this book, and middle four represent which code, i.e. X in horizontal direction,
The reading code represents the 31st code, and latter four represent which code, i.e. Y in vertical direction, and the reading code represents the 37th code.
Be stored with the first eight bits of book pages mapping table, i.e. books and the page with a reading code in point-of-reading device in advance
The mapping table of point reading code, and page number table and the mapping table of scope, that is, spread the point reading field and page number table of code generation
Corresponding relation.Point-of-reading device can obtain 3 effective informations by the parsing to a reading code：Page number information, X skews and Y skews,
Wherein, book, page information can be determined by page number information, point reading location is determined by X, Y skew, obtained by match point reading field
Audio content.
Thus the braille content obtained at the reading location can be corresponded to, if the content at such as position is " we ",
The audio content for directly obtaining " we " is played out.
Step S120：Respond the braille audio content of the corresponding acquisition of described reading code speech play.
, can be by being analyzed and acquired by a reading code by above-mentioned introduction after the point reading code put and read is identified
Point-of-reading device puts page information and point reading code X, the Y skew of the point reading location of the braille file of reading, i.e. braille file, so as to
Braille audio content corresponding with the reading location is found out in memory, then can be played out by voice, then blind person
Can be without perceiving reading braille by tactile, and Braille reading can be carried out by carrying out point reading by point-of-reading device, so as to blind
The reading of people brings great convenience, and expands the acquisition of information channel of blind person.
