Description
Technical field
The present invention relates to technical field of computer information processing, particularly a kind of two-dimensional code generation method.
Background technology
Conventional anti-counterfeiting technology, comprises bar code anti-counterfeit, two-dimension code anti-counterfeit etc. at present.Bar code is bar, the null symbol of arranging by certain coding rule by a group, in order to the information that represents that certain character, numeral and symbol form.One-dimensional bar code is called for short one dimension code, and it is different according to the width of the bar of one group of horizontal direction, thereby is weaved into a series of characters that are comprised of " 0 ", " 1 ", and this binary-coded character is encoded according to certain system agreement.The bar code of storing information at the two-dimensional space of horizontal and vertical direction, is called two-dimensional bar (2-dimensionalbarcode), is called for short Quick Response Code.From its coding principle, conventionally can be divided into following two types: row row formula two-dimensional bar code and matrix type two-dimension code.The representative matrix two-dimensional barcode of row row formula two-dimensional bar code has Code16K, Code49, PDF417 etc.The representative matrix two-dimensional barcode of matrix type two-dimension code has: CodeOne, MaxiCode, QRCode, DataMatrix etc.QRCode code (QuickResponseCode) is that Japanese Denso company is at a kind of matrix two-dimensional bar code of in September, 1994 development, it except the information capacity that has bar code and other two-dimensional bar codes and have is large, reliability high, also there is hypervelocity knowledge and magnanimity, comprehensive recognition, can represent Chinese character, and have the very strong advantages such as security and antiforge purpose.
Fig. 1 shows according to the structural representation of the Quick Response Code of prior art.Quick Response Code is a kind of of bar code.As shown in Figure 1, standard Quick Response Code by the alignment code of 4 known location and by wherein three confine greatly black and white code-point in the defined region of bit code and formed, code-point is arranged and is formed by the lattice of specific dimensions ratio.
Fig. 2 shows the generation schematic diagram according to the Quick Response Code of prior art, and wherein the coded format of matrixing has reflected corresponding data message.As shown in Figure 2, when lattice is black, represent binary code 1; When lattice is white, represent binary code 0.
The application of Quick Response Code is along with the development of network technology is also more and more extensive, and Quick Response Code can combine with current trend B/S structure, allows Quick Response Code play a role in network.As the exploitation of electronic retailing system, can adopt Quick Response Code.For example, detailed process is as follows: by the network technology of current trend, client and service provider are effectively contacted on a platform, in shopping process, add the generation interface of a Quick Response Code simultaneously, a large amount of shopping informations can be generated to two-dimension code image like this, because the storage information capacity of Quick Response Code is very large, can provide technical guarantee for add large quantity of information later.By generating the algorithm of Quick Response Code on platform, generate the Quick Response Code of corresponding information, again by the Wap technology of mobile phone, the Quick Response Code generating on platform is sent in mobile phone simultaneously, thereby completed the electronic business transaction process that generates user.The part that generates Quick Response Code in this design is core, how in network, to generate two-dimension code image, and the two-dimension code image that can make to generate takies storage space, and to try one's best little be most important.Because if two-dimension code image volume is excessive, be unfavorable for preserving, large picture format is downloaded speed decline accordingly simultaneously, be unfavorable for the client demonstration of operation system, the network two-dimension code image generating algorithm that therefore designs a kind of applicable Internet Transmission and demonstration is significant to Quick Response Code application.
Along with the universalness of ecommerce, increasing businessman need to embed the 2 D code information for doing shopping colored products propaganda picture.Yet existing Quick Response Code design proposal just generates pattern in 2 D code by chequered with black and white lattice arrangement mode, this chequered with black and white Quick Response Code cannot merge mutually with the background patterns with different color.
Therefore, for traditional antifake method for products, be necessary to propose a kind of new two-dimensional code generation method, pattern in 2 D code is blended in the background patterns with various colours, improve whole visual effect, expansion Quick Response Code business is used scope, thereby increases the business use value of Quick Response Code, is convenient to businessman and carries out the market propaganda.
Summary of the invention
The above-mentioned technical matters existing for prior art, object of the present invention aims to provide and the invention provides a kind of two-dimensional code generation method, so that pattern in 2 D code is blended in the background patterns with various colours, improve whole visual effect, expansion Quick Response Code business is used scope.
The invention provides a kind of two-dimensional code generation method, comprising: by generated data matrix after binary data coding, corresponding binary matrix data generates Quick Response Code grid pattern, and in the pre-position of described Quick Response Code grid pattern, local positioning figure is set; The color information of the background patterns that the coordinate position region in detection bit 0 data and bit 1 data place Quick Response Code grid and this coordinate position location are corresponding; When writing bit 0 data, the color information of the background patterns that the coordinate position location of detection bit 0 data is corresponding, with the color identical with background patterns, carries out painted to the coordinate position region in this bit 0 data place Quick Response Code grid; When writing bit 1 data, detect the color information of background patterns corresponding to the coordinate position location of bit 1 data, with with the akin color of background patterns, according to predefined contrast threshold X and predetermined area ratio value Y, to the coordinate position region in this bit 1 data place Quick Response Code grid, carry out painted.
