Problems solved by technology

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

Embodiment Construction

[0052] Such as Figure 1 to Figure 5 As shown, the present invention provides a coding map, which is composed of coding block a1 defined as high 20-bit coding storage capacity and coding block b2 defined as low 20-bit coding storage capacity with the same style, between coding block a and A space area is provided between the coded blocks b.

[0053] In the coding block a1 or the coding block b2 of this embodiment, one directional sequence coding unit block 3 , two CRC check digits 9 , and six data coding unit blocks 6 are respectively defined. The direction characteristic lattice sequence is used to identify the correct direction of the coding pattern, wherein the direction sequence coding unit block 3 includes a direction characteristic lattice sequence 4 composed of five direction characteristic code points 5 . Among them, five direction feature code points constitute a special-shaped image, and the sequence numbers of the direction feature code points are 0-4.

Abstract

The present invention provides a coding map, wherein each 20-bit coding block is composed of a direction sequence coding unit block, a CRC check digit, and a plurality of data coding unit blocks, and the direction sequence coding unit block includes a direction characteristic lattice sequence , the data coding unit block includes a data code point and a data reference point. The method for forming a dot matrix pattern through the above-mentioned coding diagram includes: the style of the defined direction characteristic dot matrix sequence; defining the quantity of data coding unit blocks, the distribution form of data reference points and data code points; defining the quantity of CRC check blocks, and positional relationships; converting decimal numbers into data code points embedded in code point bits; calculating the amount of code storage contained in a bitmap. The device for implementing the above method includes a direction sequence definition module, a data code list definition module, a CRC check bit definition module, a data code point formation module and a code memory calculation module. The invention can store a large amount of data information and has an anti-counterfeiting function.

Description

technical field [0001] The invention relates to an encoding pattern, in particular to a method and a device for forming a dot matrix pattern through the encoding 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 coded pattern capable of storing a large amount of data information and having anti-counterf...
