Document Type and Number:
WIPO Patent Application WO/2020/114375
Kind Code:
A1
Abstract:
A two-dimensional code generation method, comprising: determining a plurality of positioning points in a two-dimensional code to be generated (S11); determining the multi-channel assignment of information points in a positioning area where at least one positioning point among the plurality of positioning points is located, and the multi-channel assignment of information points in the area other than the positioning area in the two-dimensional code (S12); and generating the two-dimensional code according to the multi-channel assignment of the information points in the two-dimensional code (S13). A two-dimensional code generated by said method contains information about invisible positioning points, without the need of fixing the positioning points at specific positions, so that a user can acquire the two-dimensional code information merely by scanning the two-dimensional code.
