Abstract

A method and a system for recognizing location information in a two-dimensional code are provided. The method comprises: acquiring a two-dimensional code in an image (S102); performing, according to a main positioning block of the two-dimensional code, feature detection to recognize location information in the two-dimensional code (S104); and determining, according to the location information in the two-dimensional code, spatial location information of the two-dimensional code in the image (S106). Through the method, an augmented reality solution in which a two-dimensional code serves as a marker has favorable tracking performance.
