Description
Technical field
The present invention relates to two-dimensional bar code field, in particular to a kind of Chinese sensible code position detection pattern 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, the least bit printing technique using printer also 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, cause paper to be battered down, and then Chinese letter co symbol cannot be identified according to position sensing figure in visual field.
Summary of the invention
The invention provides a kind of Chinese sensible code position detection pattern and construction method thereof, in order to realize the Chinese sensible code position detection pattern that applicable stylus printer prints, make it possible in visual field, identify Chinese letter co symbol according to position sensing figure.
For achieving the above object, the invention provides a kind of Chinese sensible code position detection pattern, it comprises:
5 overlapping concentric rectangles, be respectively 7*7 dark module, a 6*6 light module, the individual dark module of 5*5 dark module, a 4*4 light module and 3*3, wherein, the length breadth ratio of modules is 1.2: 1.
For achieving the above object, present invention also offers a kind of construction method of Chinese sensible code position detection pattern, the method comprises the following steps:
Form blank rectangular matrix according to the number of modules corresponding with the version used, the length breadth ratio of rectangular matrix is 1.2: 1;
When building Chinese letter co symbolic construction, position sensing figure is inserted the relevant position in rectangular matrix, the length breadth ratio of position sensing figure module is 1.2: 1;
By the Image Saving of the Chinese letter co symbol built for setting form;
The image of setting form is outputted to 9 needle type printers according to setting resolution printing on multiple part bills.
Preferably, setting form is TIFF (TaggedImageFileFormat, Tagged Image File (TIF) Format).
Preferably, setting resolution is 120*72dpi.
In the above-described embodiments, the length breadth ratio of Chinese sensible code position detection pattern module is set to 1.2: 1, and the Chinese letter co symbol of structure is saved as the picture format of applicable stylus printer identification, and then by 9 needle type printers according to setting resolution printing on multiple part bills, Chinese letter co character position detection dimension of picture is regular, figure is clear for code, can by the identification of HR200 barcode scanner, simultaneously because the true picture print resolution employing printer prints, print point is without repeatedly overlapping, paper, without breakage, can be preserved for a long time.
