Technical field
The present invention relates to the two-dimensional bar code field, in particular to a kind of quick response matrix code position sensing figure and construction method thereof.
Background technology
QR (Quick Response, a fast response) sign indicating number standard GB/T18284-2000 has defined a kind of matrix two-dimensional barcode, standard 5.3 in introduced the quadrate array that the QR code sign is made up of square modules.In the 5.3.2 of standard, introduced the view finding figure of QR sign indicating number and formed, laid respectively at the upper left corner, the upper right corner and the lower left corner of QR code sign by 3 identical position sensing figures.Each position sensing figure can be regarded as by 3 overlapping concentric squares to be formed, and they are respectively 7*7 dark module, a 5*5 light module and 3*3 dark module.The module width ratio of position sensing figure is 1: 1: 3: 1: 1.
Module at above-mentioned standard to describe is square or name square; This dimension definitions has no problem for bar code printer, for special PRN device, such as the words of using 9 needle type printers to print; There is very big problem; At first, the true picture print resolution of 9 needle type printers is not supported horizontal and vertical identical resolution, that is to say not show good square two-dimension code; Secondly; The least bit printing technique that uses printer is the two-dimension code of the side of printing by force also; But dimension scale does not meet the requirement of two-dimension code; More serious phenomenon is significantly overlapping because of what put simultaneously, causes paper to be battered down, and then can't in the visual field, identify the QR code sign according to the position sensing figure.
Summary of the invention
The present invention provides a kind of quick response matrix code position sensing figure and construction method thereof, can in the visual field, identify the QR code sign according to the position sensing figure in order to realize being fit to the quick response matrix code position sensing figure that stylus printer is printed, to make.
For achieving the above object, the invention provides a kind of quick response matrix code position sensing figure, it comprises:
3 overlapping concentric rectangles are respectively 7*7 dark module, a 5*5 light module and 3*3 dark module, and wherein, the length breadth ratio of each module is 1.2: 1.
For achieving the above object, the present invention also provides a kind of construction method of quick response matrix code position sensing figure, and this method may further comprise the steps:
According to constituting blank rectangular matrix with the corresponding number of modules of the version that uses, the length breadth ratio of rectangular matrix is 1.2: 1;
When making up the quick response matrix code symbolic construction, the position sensing figure is inserted the relevant position in the rectangular matrix, the length breadth ratio of position sensing figure module is 1.2: 1;
The image of the quick response matrix code symbol that makes up is saved as the setting form;
The image of setting form is outputed to 9 needle type printers according to setting resolution printing to multiple part bills.
Preferable, the setting form is TIFF (Tagged Image File Format, a TIF).
Preferable, setting resolution is 120*72dpi.
In the above-described embodiments, the length breadth ratio of quick response matrix code position sensing figure module is set to 1.2: 1, and the two-dimensional code symbol that makes up is saved as the picture format that is fit to stylus printer identification; And then pass through 9 needle type printers according to setting resolution printing to multiple part bills; It is regular that the quick response matrix code character position is surveyed dimension of picture, and figure is clear for sign indicating number, can be discerned by the HR200 barcode scanner; Simultaneously because used the true picture print resolution of printer to print; Print point does not have repeatedly overlapping, and paper does not have breakage, but long preservation.
