Description
Technical field
The present invention relates to a kind of generation method of bar code symbol, particularly a kind of generation method with two dimensional bar code symbol of yard figure anchor point and the setting of auxiliary correction graph belongs to the automatic identification technology field.
Background technology
Barcode technology is an appearance coding, printing, identification, the data acquisition and processing (DAP) emerging technology that grows up on computer technology and infotech basis.People are daily see be printed on bar code in the commodity packaging, be common bar code.As an automatic identification technology, bar code is since initial stage 1970's comes out, because advantages such as its recognition is quick, accurate, reliable, cost of manufacture is low, be subjected to people's favor very soon, be widely used in fields such as commerce, taking care of books, storage, post and telecommunications, traffic and Industry Control.
Bar code is just in a direction (generally being horizontal direction) expressing information, and its certain height is normally for the ease of the aligning of reader, also causes difficulty in order to prevent that because of printing quality bad or bar code symbol damages to recognition simultaneously.The application of bar code can improve the speed of information typing, the rate that reduces errors, the part but bar code also comes with some shortcomings, for example: data capacity is less, the character set that most bar codes can be represented only is 10 numerals, 26 English alphabets and some special characters.Code 128 bar codes of bar code character set maximum, the character number that can represent are 128 ASCII symbols only; The size of bar code symbol is relatively large, and promptly space availability ratio is lower; After being damaged, bar code just can not read or the like.
Because be subjected to the restriction of information capacity, bar code only can be used for " article " are identified, and can not be described " article ".So the use of bar code, the existence of the dependency database of having to.In the place that is not having database and inconvenience networking, the use of bar code can be subjected to bigger restriction, sometimes even become meaningless.In addition, represent the occasion of Chinese character, just seem very inconvenient, and efficient be very low with bar code.
Two-dimensional bar code is in that the insurmountable problem of bar code produces in order to understand just.Because it has characteristics such as high density, high reliability, so can and represent data file (comprising the Chinese character file), image file etc. with its storage.
Two-dimensional bar code can be divided into Stacked Bar Code and matrix two-dimensional barcode.Be to arrange by the bar code layer of multirow cutting back to form on the Stacked Bar Code form, matrix two-dimensional barcode is formed with the form of matrix, on matrix respective element position, represent scale-of-two ＂ 1 ＂ with the appearance of point, scale-of-two ＂ 0 ＂ is represented in empty appearance, has been determined the implication of coded representation by the permutation and combination of point.Representative Stacked Bar Code comprises PDF417, Code 49, Code 16K etc.Representational matrix two-dimensional barcode comprises Code one, Aztec, Date Matrix, QR sign indicating number etc.Two-dimensional bar code can use laser or the recognition of CCD reader.
Comprise additional format information in the Stacked Bar Code, the information capacity maximum can reach about 1000 bytes, for example: the PDF417 sign indicating number can be used to transporting/receive the information coding of label, it is the deliver goods label substance coding of EDI ＂ on the ＂ paper as the part of ANSI MH10.8 standard, and this coding method is adopted by many industrial organizations and mechanism.But the ability maximum of Stacked Bar Code symbol canned data also has only 1000 bytes, if adopt higher error-correction level, the ability of Stacked Bar Code storage valid data can further descend.
Matrix two-dimensional barcode is compared with Stacked Bar Code, has higher information density (as: DataMatrix, Maxicode, Aztec, QR sign indicating number), can be used as the information representation symbol of packing case, in electronic semi-conductor's industry, DataMatrix or QR sign indicating number are used to identify small-sized parts.Matrix two-dimensional barcode can only be distinguished by the ccd image formula reader of two dimension, and can scan in the mode of omnidirectional.
Since two-dimensional bar code can code storage quantity of information bigger, therefore any language (comprising Chinese character) and binary message (as signature, photo) can be encoded, and can be by the level of error correction in various degree of user's selection, under the damaged situation of symbol, to recover all information.
Existing matrix two-dimensional barcode symbol, for example: the QR sign indicating number, referring to Fig. 1, because view finding figure, correction graph that it had are all alternately overlapped mutually by the different colours square.When the QR sign indicating number being distinguished and locatees, require all view finding figures all must exist, perhaps under the situation that only some view finding figure exists, must there be the correction graph of some and fixed position to exist; Otherwise just can not position, and then influence is reduced to canned data in the QR sign indicating number to it.In the case, just need use view finding figure and correction graph morely, make the corresponding minimizing of area that is used to store valid data of matrix two-dimensional barcode symbol, perhaps will store more data, just have to enlarge the area of symbol.
In order to solve the above problems, applicant's research is also developed a kind of new matrix two-dimensional barcode, the view finding figure and the distributed architecture itself thereof of this kind two dimensional bar code symbol have definite locating information, its correction graph has location and direction deixis, therefore, this new matrix two-dimensional barcode can reduce the quantity of view finding figure and correction graph as much as possible, makes bar code symbol compact more, can hold more valid data as much as possible in limited symbol area.
Referring to Fig. 2, the Chinese letter co symbol that the present invention relates to is made of the symbol module that the view finding figure 1, function information figure 5 and the correction graph 2 that are arranged on four jiaos of places, a rectangular area, auxiliary correction graph 3, digital coding and Error Correction of Coding 4 constitute.Hold in the less Chinese letter co symbol of quantity of information correction graph 2 and auxiliary correction graph 3 are not set.
But, because structurally there are certain difference in Chinese letter co and traditional matrix two-dimensional barcode symbol.The different structure of Chinese letter co is set needs the more parameter that is provided with, and therefore, when generating the Chinese letter co symbol, the generation method of classical matrix formula two dimensional bar code symbol is just inapplicable.
Summary of the invention
The object of the present invention is to provide a kind of generation method of two dimensional bar code symbol, at above-mentioned Chinese letter co, based on the code word generation Chinese letter co symbol of coded message.
The present invention includes:
Generate the view finding figure, generate the step of the positional parameter of described view finding figure simultaneously;
Generate the step of corresponding information symbol according to the code word of coded data and error correction data; And,

Embodiment
Referring to Fig. 2, the process that the present invention generates two dimensional bar code symbol comprises:
Information is encoded to the step of digital coding according to the rule of setting; Specifically be that the information flow of input or data stream are analyzed type with the character of determining to be encoded in the described information.The reason of doing like this is in order to improve the efficient to the data coding; For example: the information flow of input can comprise ASCII text character, numeral and binary data etc. usually, if these information are encoded without analyse, then might make the information that is encoded out take bigger storage space, thereby reduce the efficient of coding.And if the data that are encoded in the information flow are classified, then because the data during each is classified usually exist certain common characteristic, and can when coding, its information with general character be described, and adopt small amount of data to be described for each concrete information wherein, then can compress the information that is encoded significantly.With the example that is encoded to of above-mentioned numerical character, character " 0 "-" 9 " in computing machine with hexadecimal representation are: " 60 "-" 6A ".If adopt the coded system of not analyzing, coded character " 0 "-" 9 " then need 10 * 8=80 position binary digit.If encode after it is analyzed, then can greatly reduce this coding result.Suppose numeric string for numerical character " 0 "-" 9 " are formed, adopt 10 bits to represent that 3 decimal numeral modes encode, then the numeric string as " 84613168549316542 " can be divided into: 846,131,685,493,165 and 42 these 6 tens digits.These 6 decimal numbers are used 10 binary representation respectively, and then above-mentioned numeric string only needs 60 binary strings just can represent.Obviously, the efficient of coding is improved.If numeric string is long more, then Bian Ma efficient is high more.For the coding of text character and Chinese character, both can adopt similar mode to carry out, also can adopt the coded system that is similar in the QR sign indicating number to encode.
Owing to can form by polytype data usually in the information flow that is encoded, for example: numerical character, English text character, Chinese character etc., therefore need information be analyzed, with definite data type wherein, and encode according to corresponding type.The front and back of certain type the binary coding bit string that the coding back forms also need to add respectively pattern indication information and ending message, with convenient this coding are deciphered.
The present invention is after being encoded to digital coding with information, and the binary data bit stream that also needs further coding is finished generates corresponding Error Correction of Coding according to selected error-correction level and error correction mode.
It is common that stained or damaged situation in use appears in two dimensional bar code symbol.When occur stained or damaged after, generally can't recover coded data in the two dimensional bar code symbol.Therefore, need carry out suitable correction process, and the error correction information back of encoding is made up with coded data, form the actual total data that will form two dimensional bar code symbol and encode the data that are encoded in the two dimensional bar code symbol.Concrete Error Correction of Coding can be calculated its error-correction level according to the digital coding of reality, selects corresponding error correction mode, perhaps determines according to error-correction level and the error correction mode set in advance.The method of concrete Error Correction of Coding can realize with reference to the Error Correction of Coding generation method or the additive method of QR sign indicating number or PDF417 bar code, not do concrete qualification among the present invention.
A critical step that generates two-dimensional bar code is exactly to calculate the required size of two dimensional bar code symbol, and the size here mainly is meant the symbol module quantity that each limit of two-dimensional bar code rectangular area is required.Certainly, the required symbol module quantity in each limit of two-dimensional bar code rectangular area also can be set in advance.For example, for Chinese letter co, can calculate the size on its limit by its version number is set, concrete computing formula is: K=21+2 * N; Wherein, K is the Chinese letter co rectangle length of side, and N is the version number of Chinese letter co, and N is a positive integer.Certainly, information calculations such as the coded data that the length of side of Chinese letter co also can be by obtaining, Error Correction of Coding obtains; Concrete calculating needs to consider: all binary coded data figure places that will finally obtain add view finding figure, correction graph and the shared space of auxiliary correction graph.
Systematic function information also is the steps necessary that generates Chinese letter co; Specifically comprise the step that obtains the function information bit stream after binary number with described setup parameter, error-correction level and described two-dimensional bar code mask information makes up.Referring to Fig. 2, can be used for the space of accommodation function information in the Chinese letter co is 68 modules, and it is equally divided into 4 view finding figure places respectively, and each view finding figure place all is assigned with 17 modules.In order to guarantee that Chinese letter co is after suffering certain breakage, still can recover coded message wherein, the function information at diagonal line two ends is identical arbitrarily in the Chinese letter co, related setting parameter, error-correction level and described two-dimensional bar code mask information that the function information at adjacent two drift angle places combines and then can recover whole symbol.Particularly, the setup parameter that Chinese letter co can be used for encoding is 8 positions, and error-correction level and two-dimensional bar code mask information respectively are 2, adds up to 12, generates 22 error correction bit more on this basis, amounts to 34.34 bit function information codings just in time is divided into two 17 bit string, and after systematic function information symbol module, it is separately positioned on two adjacent view finding figure places arbitrarily.And between the symbol module that is located at described view finding image and constitutes by digital coding and Error Correction of Coding.
With upper left corner view finding figure is example, and the setting of function information module is the lower left corner from the view finding figure, is provided with to the right, after reaching the 9th module, upwards is provided with again, finishes up to the 17th module setting.The function information module at other each place, bights is arranged at that this is identical, and its setting is all carried out in the counterclockwise direction.
Referring to Fig. 2, Chinese letter co has four view finding figures, is separately positioned on four corner positions of Chinese letter co rectangular area; Referring to Fig. 3, Fig. 4, view finding figure of the present invention is overlapped by three or three above odd number rectangles, have odd number light color rectangle and the dark rectangle of even number in these three or three the above odd number rectangles, perhaps have dark rectangle of odd number and even number light color rectangle, the ratio of its corresponding length of side equates; These three or three above odd number rectangles with a same vertices by dark rectangle and the mutual intermeshing of light rectangle, perhaps by light rectangle and dark rectangle or by dark rectangle and the mutual intermeshing of light rectangle.
