Encoding pattern and method and device for forming lattice graph through encoding pattern

Abstract

The invention provides an encoding pattern. The encoding pattern comprises a plurality of encoding unit blocks, a direction characteristic lattice sequence, CRC bits, data reference points and code points. A method for forming a lattice graph through the encoding pattern includes the steps that decimal digits are converted into multi-bit binary digits; the multi-bit binary digits are combined into a plurality of binary arrays in sequence; the binary arrays are converted into digits with the scale with the number same as the number of code point bits; code points are implanted into the code point bits corresponding to the digits of the scale; decimal digits corresponding to the CRC bits are acquired and converted into binary digits; the binary digits are split, and a value is given to each CRC bit; whether the code points can be implanted into the CRC bits or not is distinguished. A device for implementing the method comprises an encoding pattern definition module, a conversion module a, a binary array forming module, a conversion module b, a code point implanting module, an operation module, a splitting module and a code point definition module. The encoding pattern can store a large amount of data information and has the anti-fake function.

Description

technical field [0001] The invention relates to a coded pattern, in particular to a coded pattern and a method and device for forming dot matrix graphics through the coded pattern. Background technique [0002] At present, most of the existing anti-counterfeiting mark patterns are generated by using coding rules similar to OID coding technology, and only a limited number of anti-counterfeiting marks can be generated. Its disadvantages are: due to the small amount of coding information stored in the anti-counterfeiting label, it is impossible to store a large amount of data information; in addition, because the coding rules similar to OID coding technology belong to the general and open coding technology, the security of the anti-counterfeiting label is reduced. performance. Contents of the invention [0003] In view of the deficiencies in the above problems, the present invention provides a coding pattern capable of storing a large amount of data information and having an...
