Example Embodiment

[0063] Example one

[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 a single positioning process is generated, that is, the process of constructing a 0-1 digital dot matrix. The size of the designated digital dot matrix is ​​9x 9, so the positioning point is a 9x 9 unit matrix, the number in the matrix is ​​0 or 1, or any combination of two different numbers, the unit dot matrix is ​​stored in the generating software database, Used to generate anchor points.

Abstract

The invention relates to the field of data identification, in particular to a two-dimensional code forming and capturing technology. The invention provides a quick positioning two-dimensional code positioning point dot matrix forming and capturing method. The two-dimensional code positioning point dot matrix forming method comprises the following steps: setting or reading a positioning point datadot matrix; drawing four centrosymmetric main positioning point lattices on a set background; and adding a positioning interval area to the periphery of the main positioning point dot matrix. The technical problems of long positioning time consumption and high positioning error rate during two-dimensional code identification are solved, the reliability of two-dimensional code positioning is enhanced, the identification efficiency is improved, and the pollution of positioning points and data is reduced.

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...
