Abstract

One of the most important problems faced when building Augmented Reality (AR) systems is registration error. In mobile and outdoor AR systems, dynamic errors are the largest source of registration errors. Hybrid tracking is a key technique in combating the effects of dynamic errors. In this paper we present a multi-stage close-loop correction algorithm for reducing dynamic registration errors in AR system. The control law in this algorithm is based on 2D visual servoing or image-based camera control that allows control of a virtual camera to reduce registration error. The experimental results illustrate the effectiveness of this algorithm.
