Two-dimensional code generation and decoding methods, apparatuses, and devices

A computing device, comprising

• a memory and a processor, wherein the memory stores executable instructions that, in response to execution by the processor, cause the computing device to:
• obtain two-dimensional code of a to-be-generated two-dimensional code image;
• perform error resilient coding on the two-dimensional code by using a coding algorithm with a predetermined error-tolerant rate, to obtain error-tolerant-processed two-dimensional code;
• determine a code element shape that is corresponding to each data information bit in the error-tolerant-processed two-dimensional code and that is in a generation region of the two-dimensional code image, wherein the code element shape comprises a dot or an arc;
• determine, according to a predetermined arrangement rule of the two-dimensional code, first position information that is corresponding to each data information bit of the error-tolerant-processed two-dimensional code and that is in the generation region;
• determine second position information of each positioning point bit in the generation region;
• and
• generate the two-dimensional code image based on the first position information, the code element shape corresponding to each data information bit, and the second position information of each positioning point bit.
