Two-dimensional code generation method, system and device for cylindrical surface

The invention discloses a two-dimensional code generation method, system and device for a cylindrical surface. The method comprises the following steps: obtaining a plane two-dimensional code and obtaining the encoding content of the plane two-dimensional code through a two-dimensional code generation tool; according to the encoding content of the planar two-dimensional code, calculating the mapping relation of the planar two-dimensional code on the surface of the target cylindrical object, and then obtaining the coordinates of each pixel point of the planar two-dimensional code ; according tothe coordinates of each pixel point of the cylindrical two-dimensional code, calling a two-dimensional code generation tool to generate the cylindrical two-dimensional code. According to the size ofthe planar two-dimensional code, the size of the target cylindrical object and the distance between the scanning equipment and the surface of the target cylindrical object, regeneration is performed to obtain a cylindrical two
