基于VR-Platform室内漫游系统技术
摘要：虚拟现实技术经过不断的发展已经被广泛的应用到各个行业中，并日趋走向成熟。近年来，室内漫游系统作为虚拟现实技术的一个分支，正在得到迅速的发展和重视。室内漫游系统的优势在于，相对于单一的图片展示，更能使用户获得身历其境的直观感受。室内漫游系统的沉浸感、交互性和构想性，是室内漫游系统的主要特点。
本文主要研究构建虚拟室内的基本原理和关键技术，包括虚拟室内的三维建模、场景实现、交互控制等。具体工作有：
（1）三维建模。采用综合几何建模和图像建模技术优点的混合建模技术。研究建筑物室内空间数据和纹理数据的采集方法并对其进行建模；基于CAD图纸模拟真实室内环境，以图片作为纹理并设定装饰材质；基于图像的平面技术对室内物品建模；采用天空盒生成天空背景；对于复杂模型，在场景中可结合使用3DS模型。
（2）虚拟场景的实现。设计实现了具有一定自由度的漫游效果；在虚拟场景中设置合理的光照、消隐以增强场景的真实感。虚拟场景中支持多种浏览模式，包括、行走、飞行、静物观察、摄像机动画。

Technology Indoor Navigation System Virtual Scene
Based On VR-Platform
Abstract: Virtual reality technology through continuous development has been widely applied to industries, and increasingly mature. In recent years, indoor roaming system as a branch of virtual reality technology, are being rapidly developed and attention. Roaming system has the advantage of interior, relative to a single image display, it enables users to access the intuitive immersive experience. Indoor Navigation System immersion, interaction, and vision, and is the main features of the indoor roaming system. This paper studies the basic principles of constructing virtual room and key technologies, including virtual three-dimensional modeling of the indoor, scene to achieve, interactive control. Specific studies include:
(1).three-dimensional modeling techniques. Integrated geometric modeling and image modeling advantages of hybrid modeling techniques. The building interior space data and texture data collection method and its modeling; CAD drawings based on simulating teal indoor environment to set the picture as a texture and decoration materials; image-based modeling of planar technology of indoor items; with the sky box generates sky background; for complex models, scenes can be combined in-3DS model.
(2).Implementation of the virtual scene. Designed and implemented with a certain degree of freedom of roaming effects; in the virtual scene set a reasonable light, blanking in order to enhance the realism of the scene. Support a variety of browsing virual scene modes including, walking, flying, still life observation, camera animation.
