Interference element is composite component 2, and composite component is arranged on the white space in information point and/or in dot pattern, and composite component is the combination of a kind of in a horizontal and vertical parity check code, lines, numeral and letter or at least two kinds.
In the time need to having implanting the article of dot pattern to distinguish, the Infrared of being sent by infrared ray recognition device can see through interference element layer and arrive at dot pattern surface, thereby the image that gets dot pattern is to carry out discriminated operant.
In addition, if adopt non-infrared ray recognition device to identify dot pattern, there will be following two kinds of situations:
Situation one,
If the spectrum of the light being sent by non-infrared ray recognition device is with identical for the spectrum of identifying interference element layer, the light being sent by non-infrared ray recognition device cannot run through interference element layer, the image of interference element layer can only be obtained, the top of dot pattern cannot be arrived at.
Situation two,
If the spectrum of the light being sent by non-infrared ray recognition device is from different for the spectrum of identifying interference element layer, the light being sent by non-infrared ray recognition device can run through interference element layer, arrive at the top of dot pattern, but, because the spectrum of its light is from different for the spectrum of identifying dot pattern, therefore, still cannot obtain the image of dot pattern.
As shown in Figure 6, this dot pattern is take code-point as least unit, and each code-point size is between 30 to 40um; The spacing (from a dot center to another Chinese and Western) of every adjacent code-point is 80um left and right; A complete coding unit piece accounts for 1.5mm*0.7mm size.Wherein, the direction reference point in dot pattern comprises Ref0 to Ref6 and Ref23, and the straight line of definition Ref0, Ref1, Ref2 composition exists the vertical relation of clockwise direction with the straight line of Ref0, Ref3, Ref4 composition.Ref7 to Ref22 is other reference point, and CRC0 to CRC5 is the code-point of CRC check code.
Only having 4 little lattice except the corresponding nine grids of Ref2, Ref5 can, for placing code-point, have 8 little lattice can supply to place code-point from 9 nine grids corresponding to Ref7 to Ref22.We define each nine grids except its center reference point, each nine grids have and only have little lattice to have code-point, be equivalent to the data volume that nine grids that Ref2, Ref5 are corresponding respectively contain 2 bit, and 9 nine grids corresponding to Ref7 to Ref22 respectively contain the data volume of 3 bit.And two corresponding data points respectively contain the data volume of 1 bit under reference point Ref23, therefore the data volume that complete encoding block contains is 2*2+3*16+2=54bit, 18014398509481984.
Only as described above, be only preferred embodiment of the present invention, such as professional who are familiar with this art.After understanding technological means of the present invention, natural energy, according to actual needs, is changed under instruction of the present invention.Therefore all equal variation and modifications of doing according to the present patent application the scope of the claims, once should still remain within the scope of the patent.
