摘要
针对增强现实中的几何一致性问题,提出了一种基于多视图几何的虚实场景位置和遮挡一致性恢复策略,该方法利用计算机视觉中的多视图几何原理同时解决了增强现实系统中的位置配准和虚实遮挡两个重要问题,在保证系统实时性的前提下,最大限度增强了真实感以提高系统可用性。实验结果表明,该文方法是有效可行的,在完成位置配准的同时解决了虚实场景之间的遮挡问题,从而有效避免了不正确的遮挡关系给使用者造成的虚实场景相对位置失真的错觉。
This paper proposes a novel method to solve pose and occlusion consistency problems by using multiple view geometry for AR systems.The method can deal with pose and occlusion consistencies simultaneously in an uniform framework,which improves the performance of AR systems obviously.Experiments have been carried out to demonstrate the validity of the proposed approach.The results indicate that the method can solve pose and occlusion consistencies problems,by which the wrong impression of relative position caused by incorrect occlusion can be avoided effectively.
