About a preferred embodiment of two dimensional code of the present invention, referring first to shown in Fig. 1, being a kind of QR code, the QR code Mainly it is provided with a data field 10 and three witness markers 11 in a square area, those skilled in the art can be with Understand: the QR code further includes calibration mark, timing mark other than above-mentioned data field 10 and witness marker 11 Will, format information and version information etc. hold further not detailed since the equal mark, information and technical characteristic of the invention are unrelated It states.
For QR code at present in respect of 40 kinds of versions (size), minimum version 1 is as shown in Figure 1, forming for 21x21 module Matrix, for version 2 then as shown in Fig. 2, for the matrix that 25x25 module forms, every one version of raising increases 4x4 module, meaning I.e. highest version is (40-1) x4+21=177, that is, the matrix of 177x177 module composition.
Two dimensional code of the invention is mainly that the witness marker 11 of QR code is utilized to provide a data write area 12, the positioning Mark 11 be in a rectangular-ambulatory-plane matrix, as shown in Figure 3A, no matter a kind of that version, the witness marker 11 is all by 7x7 The square box of block size, center is the solid construction of 3x3 block size, therefore the periphery of the witness marker 11 is in In the heart with the area without data of a square shape, the area without data is the square box that two horizontal segments and two vertical sections form, Two horizontal segments and two vertical sections are made of 5 modules respectively, and the both ends of the horizontal segment and the both ends of vertical section are respectively with one Module is overlapped, therefore the area without data actually shares 16 modules, and the present invention utilizes the witness marker 11 area without data is as the data write area 12, for supplementary data is written.
The module number of the data write area 12 data available for writing is related with the version height of QR code, the QR of highest version Yard, the data write area 12 on witness marker 11 is that write-in data are provided with the module 121~124 of four corners with (such as Shown in Fig. 3 B), imply that there are four module data available for writing for each data write area 12, and there are three witness markers for a QR code 11, that is, three data write areas 12 can be at most provided, it is total to have 12 (4x3) a module data available for writing.Low version This QR code, the data write area 12 on witness marker 11 is other than the above-mentioned data available for writing of module 121~124, institute The module 125~128 in 12 horizontal segment center of data write area and vertical section center also data (as shown in Figure 3 C) available for writing are stated, The data write area 12 of namely one witness marker 11 can have up to eight modules and at most may be used for data, a QR code is written To there is 24 (8x3) a modules, for data are written.And the data write area 12 is by horizontal segment center and vertical section center Module 125~128 for data are written, the actual size that is displayed or printed for depending on QR code determines whether to use.
Assuming that a QR code has 24 module data available for writing, 24 modules are according to different fault-tolerant grades Distribution is used as write-in data and tolerant code, for example, it can be set to 12 modules in 24 modules make data, in addition 12 make it is fault-tolerant: also can use wherein eight modules and make data, other 16 modules are made fault-tolerant.And highest version QR code has 12 modules are available for writing, therefore can set four modules and make data, and eight modules make fault-tolerant or six modules and count According to six modules are made fault-tolerant.
As above-mentioned, since the information content of highest version QR code is bigger, witness marker 11 is relatively small, therefore only takes institute The module 121~124 in four corners in data write area 12 is stated for data are written, as shown in figure 4, for convenience of description, it will wherein Four modules 121~124 of one witness marker 11a are sequentially denoted as A, B, D, C, and the four of another two witness marker 11b, 11c A module is then respectively designated as E, F, H, G and I, J, L, K, if by its data write area 12 each witness marker 11a, 11b, 11c The module of the upper half is as fault-tolerant, and the module of lower half as data, and for security consideration, do not put with fault-tolerant by corresponding data It sets in same witness marker, then fault-tolerant, the correspondence of the data of the lower half each witness marker 11a, 11b, 11c and the upper half Relationship can be for example following:
C, D, G, H, K, L=F, E, J, I, B, A
Mode as write-in data is digitized representations, that is, has filling to be expressed as 1, blank is then represented as 0.According to above-mentioned Analysis, the range that can be written into data is combined result such as following formula:
Cn=n+ (n-1)+(n-2)+...+module number (n- (n-1)) n=available for writing
And module number available for writing is different, can modify or supplement data number it is also not identical, wherein
C4=10 times, C6=21 times, C8=36 times, C12=78 times
With data write area 12 there are four module (C4) for be written data instance, so-called 10 times are to take in the following manner :
If data are A. once written on one module, count writable 4 times.
It is 3 times writable (containing for the first time) if data are B. written in two modules simultaneously for the first time.
It is 2 times writable (containing for the first time) if data are C. written in three modules simultaneously for the first time.
If data D. are written in four modules simultaneously for the first time, i.e., can only be written 1 time.
Therefore A+B+C+D=4+3+2+1=10 (secondary)
It in the aforementioned embodiment, is that eight module data available for writing are up to each data write area 12, it can Number for modification, supplementary data be as above-listed, however, when QR code is because having bigger demand on version problem or supplementary data, The data write area 12 is not limited with 16 modules, and as described in front of taking off, the data write area 12 has two levels Section and two vertical sections, each horizontal segment, vertical section can be divided into more than one and the module (such as two less than five It is a), for data are written, each horizontal segment, vertical section can also be divided into quantity and are greater than five multiple modules, such one Come, the number for modifying or being written will increase.
