Fig. 2 is the method schematic diagram of the generation Quick Response Code according to the embodiment of the present invention, as shown in Fig. 2 the embodiment of the present invention
A kind of method for generating Quick Response Code in above-described embodiment is provided, including：
Step S10, input data information is received, the code character class of Quick Response Code is determined according to the input data information
Type, release type, error-correction level and mask-type, generation clear area, rim area, positioning area and correction zone；
Step S20, according to the code character type, the release type and the error-correction level to the input data
Information is encoded, and generates data message codeword sequence；
Step S30, the code character type, the release type, the error-correction level and the mask-type are entered
Row coding, generates format version information codeword sequence；
Step S40, processing, generation data message code area, to described are masked to the data message codeword sequence
Format version information codeword sequence is masked processing, generation format version information area.
Specifically, analyzing first the data flow of input, code character type and version error correction mode are carried out true
It is fixed.Quick Response Code has several different coding patterns, and this several coding mode causes different character subsets to be converted to sign character
Efficiency is also different.If user does not have to specify the specific symbol and error correction version needed to use, selection and data should be given tacit consent to
The version most matched.
Either it is easy to produce loss of data or the wrong situation of transmission in image decoding in network transmission.In order to
Ensure the integrality of data, it is necessary in coding side using write-in redundant correcting code, codeword sequence is subjected to piecemeal on demand, made
It is corresponding with data block to obtain error correction code word.Error correction code word is generated by RS error correction algorithms, adds and entangles after code word data sequence
Error code word, when symbol damages, complete data can be obtained by error correction.
The input data information is carried out according to the code character type, the release type and the error-correction level
Coding, generate data message codeword sequence.
Final data message codeword sequence is constructed as follows.
A, code word data sequence is divided into by block according to version and error-correction level；
B, to each piece of code word data, the error correction code word of the block is calculated respectively；
C, code word data corresponding to each piece and error correction code word are included in final sequence.
Format information and version information are combined into a number by the format version information area according to certain assembling method
According to bit stream, and insert according to corresponding rule three regions of Quick Response Code code figure.Format version information codeword sequence includes content
It is as follows：Include the mask version of line number, columns, version information, error-correction level and data message.Generate format version information code word
Sequence.
Reliability when mask information is to improve recognition code is added in Quick Response Code code figure, and avoids the formation of correction
The bit stream of regional function module.Handled by following step, the purpose of mask can be met.
A, mask process is not used to functional graphic；
B, data message is subjected to xor operation with designing specific 8 mask graphs；
C, each result, the selection wherein best figure of effect are assessed.
The functional graphic includes rim area, clear area, positioning area and correction zone.
Finally, processing, generation data message code area, to the form are masked to the data message codeword sequence
Version information codeword sequence is masked processing, generation format version information area
Fig. 3 is the particular flow sheet of the generation Quick Response Code according to the embodiment of the present invention, as shown in figure 3, first, user is first
First input coding information, whether system automatic decision is beyond the maximum version capacity of Quick Response Code；System is divided data afterwards
Analysis, enter row information coding from suitable coded system, and suitable version and error correction mode are selected according to the size of information content；
Followed by the coding of data message, data bit stream is formed, and piecemeal is carried out according to corresponding version；For each piece of number
According to bit stream, corresponding error correction code word is generated by RS algorithms；Error correction code word is added after code word data sequence, is formd final
The codeword sequence given, including generation data message codeword sequence and format version information codeword sequence, and the code that filled in the blanks
Figure；Format version information and corresponding error correction information are finally respectively implanted on three angles and is masked；Finally to input
Data message codeword sequence is masked.
Fig. 4 is the decoding particular flow sheet of the Quick Response Code according to the embodiment of the present invention, as shown in figure 4, the decoding of Quick Response Code
Method is summarised as below scheme：
(1) in the decoding process of Quick Response Code, rim area positioning and identification code schematic symbol image are passed through first；
(2) format version information is distinguished (to remove mask and complete the error correction of format information, identify error-correction level and mask artwork
Shape), version information is distinguished afterwards, determines the version of symbol；
(3) bitmap of coding region is carried out with mask graph xor operation remove mask (before mask graph from
Drawn in format information)；
(4) according to module array rule, sign character is distinguished, recovers information data and error correction code word；
