Abstract

METHOD AND APPARATUS FOR GENERATING AND IDENTIFYING IDENTIFICATION CODE The present application discloses a method and an apparatus for generating and identifying an identification code. To generate an identification code, a center is first 5 determined, several concentric circles are generated based on the center, several position detection patterns that are not completely the same are generated based on the center and a specified radius, and encoding is performed on each concentric circle starting from a start pattern in the position detection patterns to generate the identification code. During identification of the identification code, the position 10 detection patterns in the collected image are first determined, and then the identification code is identified from the image starting from a start pattern in the position detection patterns. 15 FIG. 2
