  • Object on which two-dimensional code is disposed, and two-dimensional code generation method, identification method, generation apparatus, and identification apparatus
    Patent number: 10943161
    Abstract: 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
    Publication number: 20200334507
    Abstract: Embodiments of this application disclose an object on which a two-dimensional code is disposed, a two-dimensional code generation method, identification method, generation apparatus, and identification apparatus, and a storage medium. The two-dimensional code includes a square module array of m*m modules. The square module array includes a location detection pattern and a data information pattern. The location detection pattern is used for determining a location of the two-dimensional code. The data information pattern is used for carrying data. m=17 or 18 or 19 or 20. Even if printed in a miniature area whose side length is 0.5 cm to 0.7 cm, a miniature two-dimensional code provided in the embodiments of this application can still be normally identified, and is suitable for being used in a small area application scenario such as an inner side of a bottle cap or a corner of an object.

  • Method and apparatus for detecting two-dimensional barcode
    Patent number: 10755063
    Abstract: 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.
