Method for generating and reading multi-surface readable three-dimensional code

The invention relates to a method for generating a multi-surface readable three-dimensional code, and the method comprises the steps: generating a first two-dimensional code, each module of the first two-dimensional code having a two-dimensional coordinate (x, y); generating a second two-dimensional code having the same number of modules as the first two-dimensional code, each module of the second two-dimensional code having a two-dimensional coordinate (x, z) or (y, z); changing colors of modules in the first two-dimensional code or the second two-dimensional code to enable the first two-dimensional code and the second two-dimensional code to have the same number of dark color modules in the same row/column; according to the z-axis coordinates of the modules in the second two-dimensional code, z-axis coordinates of all the modules in the first two-dimensional code are set, and three-dimensional coordinates (x, y, z) of all the modules in the first two-dimensional code are obtained; and the modules with the t
