Embodiment 1

[0064] This embodiment provides a method for forming a single positioning point.

[0065] The image model of the present invention exists in the form of a 0-1 digital dot matrix in the software, so the process of generating a single positioning is the process of constructing a 0-1 digital dot matrix. Specify the size of the digital lattice to be 9x9, so the positioning point is a 9x9 unit matrix, the number in the matrix is ​​0 or 1, or any combination of two different numbers, and the unit lattice is stored in the database of the generating software. Used to generate anchor points.

Embodiment 3

[0078] This embodiment provides a two-dimensional code positioning point dot matrix capture method, such as Figure 5 shown, including:

[0079] Step 1: Obtain the QR code image, process the image to obtain dot matrix data;

[0080] Step 2: Capture the 9*9 sub-lattice A at the end according to the order of the lattice;

[0081] Step 3: Judging whether there are more than 80% anchor point intervals around the sub-lattice A, if not, return to step 2;

[0082] Step 4: Determine whether the sub-lattice A is consistent with the standard positioning point data in the database, if not, return to step 2;

[0083] Step 5: mark the above-mentioned sub-lattice A as the first main anchor point lattice A;

[0084] Step 6: Based on dot matrix A, move down 3*Y unit length distance to capture 9*9 sub-dot matrix B; take sub-dot matrix A and B as the basis, move to the right by 3*X unit length distance, respectively Take two 9*9 sub-lattices, marked as sub-lattice C, sub-lattice D;

Description

technical field [0001] The invention relates to the field of data identification, in particular to the formation and capture technology of two-dimensional codes. Background technique [0002] Two-dimensional codes are usually in the form of a matrix array. The encoding and decoding start from the designated starting point of the matrix array. Accurate and fast reading of the positioning starting point is the key to ensure successful decoding. [0003] Prior art one is the Chinese patent application whose patent publication number is CN102034127A, and its technical scheme is as follows figure 1 shown. It discloses a large-capacity two-dimensional barcode system and a coding method thereof. The shape and characteristics of the positioning point of the invention are not clear enough, and it is easy to be confused with other content, resulting in a long time-consuming identification and positioning process of the positioning point; without auxiliary positioning points, the pro...
