摘要
基于图像绘制的虚拟环境构造是近年来虚拟现实技术研究的热点。通过分析三维导航的原理和虚拟现实建模语言的插值算法,本文提出一个基于图像系列的三维导航系统快速实现的方法。首先对三维导航的路径进行分析来定义关键帧节点,利用数码相机依照关键帧节点依次采集到一系列的图像,并结合VRML编程语言的插值节点,定义多种漫游行走方式的程序原型,对图像系列进行插值,生成漫游的三维导航视频,从而简单快速地实现室内外的三维导航,实践证明该方法成本低,制作简便,效果好。
The reconstruction of Virtual Reality Scene based on image has become the hot topic in last ten years. By analysising the process of 3D navigation and the interpolation method of Virtual Reality Model Language, a novel method about the implement of 3D Navigation based on series image set is presented in this paper. Firstly, the definition of key flame point is presented through the analysis of 3D navigation route, and the images are obtained by digital camera in accordance with the key flames. Secondly, all kinds of roaming prototype are defined by the interpolation node of VRML program. Lastly, the navigation animation by the interpolation of the series image is generated, which efficiently implement the 3D navigation of indoor and outdoor. The experiment show that technique is cheaper and simpler, also has good performance.
