Two-dimensional code and method, terminal, and apparatus for recognizing two-dimensional code

An apparatus for recognizing a radially-distributed two-dimensional code, comprising:

• a processor and a memory, the memory storing computer readable instructions, and the computer readable instructions being executed by the processor to perform operations comprising:
• selecting, from pixels of the radially-distributed two-dimensional code, a pixel comprised in a code element in an encoding region of the radially-distributed two-dimensional code;
• determining a value of the code element in the encoding region according to the pixel comprised in the code element in the encoding region;
• and
• recognizing the radially-distributed two-dimensional code according to the value of the code element in the encoding region, wherein the radially-distributed two-dimensional code comprises at least two radially-distributed strip-shaped regions radially extending from a center region of the radially-distributed two-dimensional code to an edge region of the radially-distributed two-dimensional code, the at least two strip-shaped regions formed by aggregation of code elements of the radially-distributed two-dimensional code.

A terminal, comprising:

• a processor, configured to:
• select, from pixels of a radially-distributed two-dimensional code, a pixel comprised in a code element in an encoding region of the radially-distributed two-dimensional code;
• determine a pixel comprised in each code element by querying a pre-established mapping relationship according to an identifier of each code element in the encoding region, the mapping relationship being a mapping relationship between the identifier of each code element and the pixel comprised in each code element in the radially-distributed two-dimensional code;
• determine a value of the code element in the encoding region according to the pixel comprised in the code element in the encoding region;
• and recognize the radially-distributed two-dimensional code according to the value of the code element in the encoding region;
• and
• a display device, configured to display an identification result of the radially-distributed two-dimensional code.
