Registration correction for augmented reality in E-commerce

Abstract

Current E-commerce technologies cannot provide enough information to buyers. By overlaying virtual information of products on the real world, Augmented Reality (AR) technology might improve the performance of E-commerce. Too many registration errors are the key hindering factors in AR actual system. 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. ©2009 IEEE.
