摘　　要：文章结合最新的交互式自由立体视频技术与露天开采虚拟现实技术,设计并实现了一种基于自由立体视频的露天矿开采虚拟现实技术的交互与演示系统。文章利用3DS Max和VRMap软件建立了某露天矿区的虚拟视觉模型,并将这些虚拟视觉模型按照适合立体显示的条件进行场景渲染和视频图象生成,最后结合虚拟场景的三维显示特性设计了交互式自由立体视频软件,通过该软件展示了虚拟现实场景。该系统克服了传统虚拟现实演示的局限性,用较低的成本支持更多的用户进行参与和交互,同时也具有较强的环境拓展性。The paper designed and realized a kind of interaction and demonstrating system based on free-viewpoint stereoscopic video of surface mining virtual reality technology combining with the newest interactive free-viewpoint stereoscopic video technology and surface mining virtual reality technology. It established virtual visual model of a surface mine using 3DS Max and VRMap software, further more, scene romance and video image creation of such models were carried out in accordance with conditions fit to proper tidimensional display. At last, it designed interactive free-viewpoint stereoscopic video software combining with three-dimensional demonstrating characteristics of virtual scene, by which virtual reality scene was shown. The system overcame localization of traditional virtual reality demonstrations and entitled more users to participant in and interact with lower cost. The system owned stronger environmental expansion at the same time.
