摘　　要：将图像和几何模型相结合,对于需要操纵和改变外观轮廓形状的目标视景采用基于几何模型的方法建模,对于环境视景采用基于图像(IBR)的方法建模,并对这两种模型进行图像合成,实现的场景既具有很好的真实感,又具有很好的实时性和可操纵性。实现了一个图像和几何模型相结合的虚拟视景系统,介绍了系统的结构、目标视景三维模型生成、环境视景全景图的拼合及虚拟场景图像合成与显示等关键技术。The kernel and foundation of virtual reality are the constructions of virtual environment and to handle the environment friendly. In order to represent real world precisely, the hybrid approach using geometric modelling and image-based rendering is promising. Taking the advantages of geometric modelling and image-based rendering, a virtual environment construction and real-time graphics generation system that supported photographs and geometric modeling was developed on microcomputer. The structure, functions, typical examples and some key technical details of the system were proposed.
