Abstract
(EN)
The invention aims to provide a method for generating a two-dimensional code. The method comprises the steps of determining a plurality of positioning points in the two-dimensional code to be generated; According to at least one positioning point in the plurality of positioning points, determining multi-channel assignment of the at least one positioning point in an information point in a corresponding positioning area in the two-dimensional code and multi-channel assignment of the information point in other areas except the positioning area in the two-dimensional code, the assignment of the information point in a first channel in the other areas satisfying a first distance correlation; And generating the two-dimensional code according to the multi-channel assignment of the information point in the two-dimensional code. The two-dimensional code generated based on the scheme contains invisible positioning point information, the positioning point does not need to be fixed at a specific position, and a user can acquire the two-dimensional code information by scanning the two-dimensional code.
