摘要

摘要: 增强虚境技术在基于图形的建模与绘制(GBMR)框架下利用基于图像的建模与绘制(IBMR)方法描述复杂对象及加速场景绘制,可以解决虚拟现实研究中逼真绘制与实时显示间的矛盾.将国内外增强虚境方面的最新研究成果按融入合成场景中图像对象包含几何信息的比例划分成3大类,分别是在合成场景中融入纯图像对象、融入部分几何信息的图像对象及利用IBMR方法加速场景绘制,介绍了3类工作中新的研究成果,分析了这些成果的基本原理、方法、过程和优缺点,提出了该领域技术发展面临的5大问题及可能的解决方法．

Abstract: Augmented virtuality(AV) is a kind of technology which can be used to describe very complex models and accelerate rendering with images based modeling and rendering(IBMR) under the framework of graphics based modeling and rendering(GBMR). It can decrease the conflict between realism display and real-time rendering in virtual reality. The major work about augmented virtuality was classified into three categories according to the proportion of geometric information in the scene image objects, with no geometry, implicit geometry and using IBMR to accelerate rendering. Some representative work in these categories was surveyed and compared to the theory,method,process. Five problems in future research were provied and possible way to solved them were present.
