Detailed Description
The invention will be further described with reference to the accompanying drawings in which:
as shown in fig. 1, the two-dimensional code generation method of the present invention includes the following steps:

s4, presetting a depth value for each sub-unit;
and S5, processing the depth of each subunit on the surface of the object according to the preset depth value to form the target two-dimensional code.
Preferably, the initial two-dimensional code includes a first region and a second region; the first area is used for storing positioning identification information; the second area is used for storing the subunits. Preferably, the first area is arranged outside the second area, so that the range of the two-dimensional code can be rapidly located when the two-dimensional code is detected and read.
Preferably, the encoding information at least comprises a first encoding value and a second encoding value; the first encoded value is shown to be different from the second encoded value.
Preferably, in S4, the same depth value is set for the sub-cells having the same coding information, and different depth values are set for the sub-cells having different coding information.
Preferably, the subunit is a rectangular frame.
Preferably, the processing manner in S5 is punching or grooving.
Specifically, a two-dimension code identification database is established; acquiring product information for distinguishing a product from other products, such as an original product code, and generating a DataMatrix two-dimensional code as an initial two-dimensional code by using a computer through the original code; the DataMatrix two-dimensional code adopts M-N (M and N are both more than or equal to 8) rectangular frames with the lattice size as subunits of an initial two-dimensional code, different character information can be stored in the subunits, such as characters '1' and '0', punching is carried out in the subunit rectangular frame with the character '1', no punching is carried out in the subunit rectangular frame with the character '0', the depth value of the punched subunit rectangular frame is taken as a first depth value more than zero, the depth value of the non-punched subunit rectangular frame is taken as a second depth value equal to zero, the subunits with the first depth values and the subunits with the second depth values are jointly arranged and combined to form coding information with the characters '1' and '0', the set of all the subunits is taken as a coding area of the two-dimensional code of the invention, punched positioning rectangular frames are further arranged at the upper left part, the lower left part and the lower right part of the periphery of the coding area, positioning holes are punched in the positioning rectangular frames, the method is used for quickly identifying the range of the two-dimensional code. As shown in fig. 2, in the initial two-dimensional code, the sub-unit rectangular frame with the shaded area corresponding to the character "1" is set as the first character rectangular frame, and the sub-unit rectangular frame with the blank area corresponding to the character "0" is set as the second character rectangular frame.
The invention codes the product information into the two-dimensional code and realizes the processing of the two-dimensional code on the product by controlling the depth of the punching. In the process of reading and verifying, the character data of the subunit codes are judged by identifying the depth of the open holes of the rectangular frame of the two-dimensional code subunit or detecting whether the subunit opens the holes, so that the initial two-dimensional code is generated, and the original product code information is obtained by reading the initial two-dimensional code information.
The two-dimensional code generation method has the characteristics of storing ultra-large capacity information and higher safety; the two-dimensional code has strong error correction capability, and even if the surface of a product is partially worn, original information can be accurately decoded; compared with the traditional two-dimension code, the two-dimension code has the characteristics of altering prevention and low possibility of abrasion, and in addition, the one-to-one relation between the two-dimension code and a product can be ensured, so that the product is prevented from being turned and wrapped.
The technical solution of the present invention is not limited to the limitations of the above specific embodiments, and all technical modifications made according to the technical solution of the present invention fall within the protection scope of the present invention.
