实景空间中虚拟对象嵌入技术研究

Virtual Objects Registration in Imaging Space

实景空间是以实景图像为素材构造出的具有三维操纵能力的虚拟空间,增强现实技术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。该文主要讨论如何在实景空间中嵌入计算机生成的虚拟对象。首先介绍了实景空间的概念和模型,然后着重探讨了虚拟对象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。

Imaging space is a virtual space constructed from the real image.Augmented Reality can merge computer-generated virtual object or other addition information into the user's view of the real world.We focus in this paper on the problem of adding computer-generated virtual objects into image space.This paper introduces the definition and model of imaging space at first,and then presents the methods of combining the virtual objects with image space,which lays emphasis on the geometrical consistency and photometric consistency problem.
