Abstract

The invention provides a graphic code generation method and device, a graphic code recognition method and device and electronic equipment. The graphic code generation method comprises the following steps: acquiring target information; performing information deformation on the target information to obtain error correction information; generating an information code according to the target information, and generating an error correction code according to the error correction information; and generating a corresponding graphic code according to the information code and the error correction code. According to the embodiment of the invention, the information code and the error correction code which contain the same content are generated in the graphic code, so that the graphic code has a good error correction rate, and even if the graphic code is covered with a dirty part, the graphic code can be accurately identified, and thus the multi-polluted working environment of storage, materials and the like can be adapted to, and the identification efficiency of the graphic code is improved.

Description
