Abstract

The invention relates to a method and device for determining a two-dimensional code area, equipment and a storage medium, and the method comprises the steps: obtaining a to-be-recognized image which comprises a two-dimensional code gray-scale image, wherein the two-dimensional code gray-scale image is a rectangular image; determining gray scale change information of each side of the two-dimensional code gray scale image in a projection direction, establishing a two-dimensional coordinate system in a direction in which two adjacent sides of the two-dimensional code gray scale image are located,the projection direction being a transverse axis direction or a longitudinal axis direction of the two-dimensional code gray scale image; and determining a two-dimensional code area in the to-be-identified image according to the gray scale change information of each edge in the projection direction. The method and device are used for solving the problems that the black background or dark background two-dimensional code cannot be effectively recognized, the recognition time is long, and the recognition difficulty is high.
