Abstract: The 3D tracking registration technology is an important key technology in the field of augmented reality. By tracking and locating images or objects in a real scene, the virtual objects are superimposed into the real scene according to the correct spatial perspective relationship. This paper comprehensively introduces the 3D tracking registration technology in augmented reality, elaborates the advantages and disadvantages of different tracking registration methods, introduces the current application status of different tracking registration methods, and then discusses the development trend and existence of tracking registration technology. The problem is further explored by the further study of 3D tracking registration technology.
