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.
