A two-dimensional code, a two-dimensional code generation method, identification method, generation apparatus, and identification apparatus, and a storage medium are provided. The two-dimensional code includes a square module array including an array of m*m modules, a location detection pattern and a data information pattern. The location detection pattern determines a location of the two-dimensional code, the data information pattern is configured to carry data information, each module of the array of m*m modules is at least one of a first-type module and a second-type module, a color attribute of the first-type module is different from a color attribute of the second-type module, and m is at least one of 17, 18, 19, and 20.

Object on which two-dimensional code is disposed, and two-dimensional code generation method, identification method, generation apparatus, and identification apparatus

A method for detecting a two-dimensional barcode is provided. Binarization processing is performed on an image to obtain a binary image. Whether the binary image has a target pattern is determined, and it is determined that the binary image has a two-dimensional barcode in response to determining that the binary image has the target pattern. An enlarged image of the two-dimensional barcode is obtained, and two-dimensional barcode detection is performed on the enlarged image of the two-dimensional barcode.
