OBJET POURVU D'UN CODE BIDIMENSIONNEL, PROCÉDÉ DE GÉNÉRATION DE CODE BIDIMENSIONNEL, ET PROCÉDÉ ET APPAREIL DE RECONNAISSANCE

摘要

Disclosed are an object provided with a two-dimensional code, a method for generating a two-dimensional code, a recognition method, a generation apparatus, a recognition apparatus and a storage medium. The two-dimensional code is composed of a square module array in the form of m modules * m modules. The square module array comprises a position detection graph and a data information graph. The position detection graph is used for determining the position of the two-dimensional code. The data information graph is used for carrying data, wherein m = 17, 18, 19 or 20. Even though the miniature two-dimensional code provided in the embodiment of the present application is printed into a miniature region with the length of a side being 0.5-0.7 cm, recognition can be performed normally, and thus the two-dimensional code is suitable for use in a small-region application scenario, such as the inner side of a bottle cap, the corner of an object, etc.
