So that it is determined that mask corresponding with binary array.
In practice, two dimensional code provided by the embodiments of the present application includes multiple versions.The two dimensional code of different editions corresponding two
The quantity of system number is different.Therefore, the information capacity of the two dimensional code of different editions is also different.In general, version is higher, first is default
The quantity for the preset that sequence includes is more, and the information that two dimensional code can accommodate is also just corresponding more.
In some optional implementations of the present embodiment, above-mentioned executing subject can determine and two as follows
The corresponding mask of system array:
Firstly, generating preset number mask in the way of recycling core.
Wherein, it is exactly to pass through recursive traversal n (n is positive integer) bit that mask is generated in the way of recycling core
All situations, and remove full 0 and it is complete 1 the case where, obtain the binary array of remaining situation.Here it is possible to from the 1st to n-th
A array element sets 0 respectively and sets 1, then after the array element all from 1 to n all sets 0 or set 1, can be obtained n
The all situations of binary number.For example, generating the binary array that digit is 3,4,5,6 first with traversal mode.Wherein, position
Number is 8 for the number of 3 binary array, and the number for the binary array that digit is 4 is 16, the binary system that digit is 5
The number of array is 32, and the number for the binary array that digit is 6 is 64.Then the binary array of full 0 and complete 1 is removed
Afterwards, 112 masks can be obtained.
Later, for a mask in preset number mask, mask is carried out to binary array using a mask
Operation obtains the corresponding mask operation result of a mask.
Typically for any one mask in preset number mask, it is performed both by this step.Wherein, mask operation is
Position and operation are carried out using mask pair binary array corresponding with character string.

According to and be drawn homochromy dot and link together to two dimensional code identification impact, can be from the point of the inside in fish body region
Selecting mutually non-conterminous point is used as preset to generate the second predetermined sequence.
Step 305, error correcting code is added in binary array.
In the present embodiment, for the ease of error correction, what is stored in the coding region of two dimensional code is usually to be added to error correcting code
Binary array.Wherein, error correcting code can be the code for occurring voluntarily to find or correct after mistake in decoding process.To make
A kind of code has error correcting capability, must increase true form word extra symbol, to expand the difference between code word, i.e., true form word be pressed
Certain rule becomes the code word for having certain redundancy, and makes have certain relationship between the code of each code word.Code word reaches receiving end
Afterwards, whether can be met according to coding rule to determine whether mistake.When not being able to satisfy, by where the determining mistake of certain rule
It is simultaneously corrected position.Here the error correcting code added is usually RS error correcting code.
Step 306, mask operation is carried out to binary array using mask corresponding with binary array.
In the present embodiment, above-mentioned executing subject can use the corresponding mask of binary array to being added to error correcting code
Binary array carries out position and operation, to obtain the binary array after mask operation.Using mask to binary array into
Row mask operation, storing to the binary array after mask operation can make the distribution of color of two dimensional code more uniform.
Step 307, the binary number in the binary array Jing Guo mask operation is sequentially stored in the coding of the Diagram of the Supreme Ultimate
In the first predetermined sequence in region, two dimensional code corresponding with character string is generated.
In the present embodiment, above-mentioned executing subject can be by the binary number pair in the binary array Jing Guo mask operation
The particular geometric figure answered successively is plotted in the first predetermined sequence in the coding region of the Diagram of the Supreme Ultimate, thus generation and character string
Corresponding two dimensional code.
