摘　　要：增强现实可以把计算机产生的虚拟物体或其他信息合成到用户看到的真实场景中.本文将增强现实技术与基于图像的绘制技术有机的结合起来,研究并实现了一个基于增强现实技术的虚拟实景空间系统.首先介绍了虚拟实景空间的构造,然后着重探讨了虚拟物体与实景空间的合成方法,主要解决合成中的几何一致性和光照一致性问题.Augmented Reality can merge computer-generated virtual objects or other addition information into the user＇s view of the real world. This paper uses AR technique and IBR technique to construct an Image-based Virtual Space system, which can add computer-generated virtual objects into the real image space. We introduce the process of building the Image-based Virtual Space at first, and then present methods of combining the computer-generated virtual objects and the real image space on emphasis, which mainly resolve the geometrical consistency and photometric consistency problem.

关 键 词：虚拟现实 增强现实 虚拟实景空间 虚实合成
