基于虚拟现实的中国古建筑虚拟重建

Virtual Reconstruction of Chinese History Architecture Based on Virtual Reality

虚拟现实是数字图像处理、计算机图形学、计算机视觉、人机交互等多项技术的综合应用。本文针对中国古建筑的特点,应用虚拟现实技术,对毁于1860年战火的我国著名古典园林圆明园的部分典型建筑实现了虚拟重建。虚拟重建的过程主要包括数据获取、场景建模、漫游系统和实时渲染等。虚拟重建圆明园系统以圆明园中的单个景点为例,提供了含多种漫游方式的人机交互系统,对应用虚拟现实技术于中国古建筑保护进行了有益的尝试。

Virtual reality is a combination of image processing, computer graphics, computer vision, human-computer interaction and so on.With virtual reality,we have made a virtual reconstruction to Yuanmingyuan,the famous royal palace ruined in the war of 1860s.The process of virtual reconstruction consists of data acquiring,modeling,rendering and real-time browsing system designing.Our system selects single sight of Yuanmingyuan as example,supporting three browsing modes including free browsing,restrained browsing and applying of virtual reality technology to the protection of Chinese route browsing.It provides a beneficial attempt to the history architecture.
