Kind Code:
A1
Abstract:
Provided are a method for building a dot matrix code, a method for generating and reading a dot matrix code, a terminal, and a dot matrix code system. The method for building a dot matrix code comprises the following steps: building N x N information elements arranged in a matrix; configuring the information elements into information unit modules or flag unit modules; in the information unit modules, storing different values on the basis of the relative positions of information points in the information elements; and in the flag unit modules, identifying dot matrix code identification information on the basis of the arrangement manner of the information points in the information elements. By means of the method for building a dot matrix code, the method for generating and reading a dot matrix code, the terminal, and the dot matrix code system of the present invention, a dot matrix code which has an even distribution and an information hiding function can be provided, and requirements of actual application scenarios can be satisfied.
