Embodiment 1
[0054] figure 1 A schematic structural diagram of a dot-matrix two-dimensional code provided by an embodiment of the present invention is shown.
[0055] A predetermined number of code points are distributed on the dot-matrix two-dimensional code 10 . The dot matrix two-dimensional code 10 is provided with at least one code area 100 , and the code area 100 includes at least one data column 110 and at least one positioning column 120 . The data columns 110 and the positioning columns 120 are periodically arranged alternately.
[0056] In this embodiment, the code area 100 includes a 6*6 point set, that is, 3 data columns and 3 positioning columns arranged alternately periodically, and each data column and each positioning column contains 6 code points. In other embodiments of the present invention, the code area may also include point set areas of other sizes.
[0057] In this embodiment, the shape of the code point is square. In other embodiments of the present invention, ...
