Abstract

The invention discloses a method and system for identifying the two-dimensional code position. The method comprises steps that a two-dimensional code of an image is acquired; characteristic detection is carried out according a main positioning block of the two-dimensional code, and the position information of the two-dimensional code is identified; the space position information of the two-dimensional code in the image is determined according to the position information of the two-dimensional code. Through the method, an augmented reality scheme taking the two-dimensional code as a marker has the excellent tracking effect.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and system for identifying the position of a two-dimensional code. Background technique [0002] Augmented reality technology (Augmented Reality, referred to as AR) is a new technology that "seamlessly" integrates real world information and virtual world information. Visual information, sound, taste, touch, etc.), through computer technology, simulated and then superimposed on the real world to be perceived by human senses, so as to achieve a sensory experience beyond reality. [0003] In the prior art, the augmented reality technology with a two-dimensional code as a marker (Marker) mainly has the following two implementations: [0004] (1) Two-dimensional code outline method. [0005] This scheme uses the outline of the two-dimensional code as the feature point set, and the system presets a set of feature points for the outline of the two-dimensional code...
