Description
Technical field
The present invention relates to two-dimensional bar code field, in particular to a kind of Chinese letter co and construction method thereof.
Background technology
Chinese letter co standard GB/T/T21049-2007 defines a kind of matrix two-dimensional barcode, and in 5.2 of standard, introduce Chinese letter co symbol is the quadrate array be made up of n nominal square modules.The view finding figure introducing Chinese letter co in the 5.2.2 of standard is made up of 4 position sensing figures, lays respectively at the upper left corner of Chinese letter co symbol, the upper right corner, the lower left corner and the lower right corner.Position sensing feature size is 7*7 module, from structure, 5 overlapping square compositions different according to the size of lower right corner alignment can be regarded as, they are respectively 7*7 dark module, a 6*6 light module, a 5*5 dark module, a 4*4 light module, a 3*3 dark module, and the characteristic ratio of its scanning is 1: 1: 1: 1: 3 and 3: 1: 1: 1: 1.In the placement of position sensing figure, the position sensing figure in the lower left corner is that the position sensing figure dextrorotation in the upper left corner turn 90 degrees and obtains, the position sensing figure in the lower right corner is that the position sensing figure dextrorotation in the lower left corner turn 90 degrees and obtains, and the position sensing figure in the upper right corner is that the position sensing figure in the lower right corner is rotated counterclockwise 90 degree and obtains.In other parts of 5.2, further describe each several part feature of the symbolic construction composition of Chinese letter co.
The module described in above-mentioned standard is square or name square, this dimension definitions for bar code printer without any problem, but for special printing device, such as use the words that 9 needle type printers print, there is very large problem, first, the true picture print resolution of 9 needle type printers does not support horizontal and vertical identical resolution, does not that is show good square Quick Response Code; Secondly, use the least bit printing technique of printer, can the Quick Response Code of the side of printing by force, but dimension scale does not meet the requirement of Quick Response Code, more serious phenomenon is because the significantly overlap of point simultaneously, causes paper to be battered down, what general use stylus printer printed is all legal bill, need long-term preservation, paper is battered down just to be done at that time, took out use again after saying nothing of long-term preservation.In this case, the related definition in Chinese letter co standard just cannot be applied, and needs to make improvement.
