A Registration Method in Augmented Reality
一种增强现实系统的三维注册方法

Augmented reality(AR) is a technology in which a user's view of the real world is enhanced or augmented with additional information generated from a computer model.One of the key issues in the implementation of augmented reality is the registration problem. Synthetically,vision based registration can offer superior solutions. In several existing registration methods, 2 D objects or pictures are used as positioning fiducials, and at least two cameras and/or separate tracking subsystems are needed. In this paper, a new registration method is proposed which uses a solid fiducial and a single color CCD camera. The new method significantly simplifies the registration system and algorithm, and coordination errors are eliminated. The algorithm requires little computation and can be easily realized in real time without latency.
