Abstract
A method for writing the image recognizing software of QR code features that when the image of code signs is a square-like matrix image composed of several circular modules, the circular module is defined as a square module with side lenggh equal to the diameter of circular module. Then a standard coding program is run. A recognizing algorithm is also disclosed.
Description
The present invention relates to computing machine bar code automatic identification technology, refer in particular to the preparation method of the image recognition software of GB GB/T18284-2000 " quick response matrix code QR Code " (being called for short " QR sign indicating number ") QR sign indicating number.
Computing machine bar code automatic identification technology comprises bar code and two-dimension code, two-dimension code has can represent Chinese character information and picture information, carry technological merits such as containing much information, can accurately describe, prevent to forge, can not rely on Computer Database, thereby improved the application level of barcode technology, expanded the application of barcode technology.
GB GB/T 18284-2000 " quick response matrix code QR Code " is representative two-dimension code, the technical stipulation among the GB GB/T 18284-2000, " each QR code sign be made up of square modules a quadrate array constitute ".The QR code sign has 40 specifications, is respectively version 1, version 2 ... edition 40.The specification of version 1 is 21 modules * 21 modules, and the specification of version 2 is 25 modules * 25 modules, and the like, each version symbol increases by 4 modules than the every limit of last version, and up to edition 40, its specification is 177 modules * 177 modules.
In the practical application, the higher printing output device of resolution that the requirement of the code sign of QR sign indicating number uses a computer and controls is as hot transfer ribbon code printer, laser printer.Save most so that carry the printing area of the code sign of equal quantity of information.
The code sign of QR sign indicating number is when using horizontal sliding pin type slip printer prints, for realizing that each module must be the code sign technical requirement of square modules, module need be amplified, form a foursquare module so that use the circular pin mark (annotate: the print needle of stylus printer is circular minute hand, and its diameter is about 0.19mm) of several stylus printers.This technical requirement causes when using the code sign of horizontal sliding pin type slip printer prints QR sign indicating number, and the quantity of information of carrying is certain, compares with normal code sign area occupied, take the above area of several times.This result has formed following problem:
At first, two-dimension code is an advantage to contain much information, and the user who selects for use two-dimension code to manage for realizing personalized accurate description, has organized bulk information in code sign.
Based on above-mentioned situation, the printing area requirements of code sign is as far as possible little, carries maximum quantity of information to reach in the code sign area of minimum.
Simultaneously, because two-dimension code is a kind of service administrative skill, it need friendlyly with various applied environment be connected or embed.That is to say that it should satisfy user's demand, rather than require the user to go to be suitable for it for management.
In the real life, the specification of various certificates, bill, shape, font, layout etc. determine that all the planar bar code technology symbol that forms to new development does not leave big blank and prints the space of a whole page.For example: the value-added tax invoice can use the QR sign indicating number to manage, and with the quick typing of realization information, the inspection of strengthening intersecting is checked, and hits the lawbreaking activities of tax evasion.But, the accurate management expectancy quantity of information of invoice is more, and that invoice can be printed the effective blank area of QR code sign is very little, using slip printer prints QR code sign the code sign module must be amplified again according to the technical standard of GB GB/T 18284-2000 uses several round dots to form square to satisfy the standard of square modules, both form contradiction, cause the technology popularization difficulty.
Chinese invention patent application " the printing shape of quick response matrix code symbol " (application number: 01120234.3) provide a kind of printing shape of new quick response matrix code symbol, the printing shape of " quick response matrix code " code sign is changed into round die block by square modules, coding is still deferred to the GB technical requirement with interpretation method, changes the single square modules symbol of the identification in the image recognition software into compatibility in the application and discerns the round die block symbol.This invention can be with the circle seal that knocks formation each time of the print needle of stylus printer o'clock as an identification module, also can be with the luminous each time circular light spot of article surface that burns of laser marker as an identification module, the characteristics that make full use of bill printer and laser marker are applied GB/T 18284-2000 National Standard quick response matrix code effectively ", the problem how the image recognition analysis software that above-mentioned new circular code sign module needs to solve the code sign image recognition apparatus in actual applications combines the standard interpretation method of the recognition methods of the code sign of newly-designed round die block and GB technical requirement.
The purpose of this invention is to provide a kind of preparation method of code sign image recognition software of QR sign indicating number, so that the automatic identification of the QR code sign of this round die block is connected with the technical requirement of identification square modules among the GB GB/T18284-2000.
The object of the present invention is achieved like this: the preparation method of the image recognition software of QR sign indicating number, the approximate foursquare matrix image that the image of its code sign is made up of several round die blocks, it is characterized in that when the image recognition software program of this code sign of establishment, round die block is defined as a foursquare inscribed circle, assert that this round die block is the square modules that a length of side equals this round die block diameter length, then, entering the standard translator deciphers.Also can when the image recognition software program of this code sign of establishment these round die blocks in this matrix image be defined as the square modules that a length of side equals this round die block diameter length, then, the standard translator of entering is deciphered.
Specify below in conjunction with embodiment:
Figure one is the code sign example of GB/T 18284-2000 " quick response matrix code "
Figure two is two kinds of different code sign modular shape
Figure three is the code sign examples of new " quick response matrix code "
Among the figure: 1 code sign; 2 position sensing figures; 3 correction graphs; 4 square modules; 5 round die blocks.
The preparation method of the image recognition software of QR sign indicating number, the approximate foursquare matrix image that the image of its code sign 1 is made up of several round die blocks 5, it is characterized in that when the image recognition software program of this code sign 1 of establishment, round die block 5 is defined as the inscribed circle of a square modules 4, assert that this round die block 5 is the square modules 4 that a length of side equals this round die block diameter length, then, entering the standard translator deciphers.Also can when the image recognition software program of this code sign 1 of establishment these round die blocks 5 in this matrix image be defined as the square modules 4 that a length of side equals these round die block 5 diameter lengths, then, the standard translator of entering is deciphered.
Advantage of the present invention is: this new QR code image recognition software preparation method, can During approximate foursquare matrix image that the image of code sign is made up of several round die blocks, When working out the image recognition software program of this code sign, round die block is defined as a length of side etc. In the square modules of this round die block diameter length, then, the Engage of standard translator carries out Decoding. This invention provides the recognizer of round die block code sign, and is simple, practical.
