摘　　要：为了紧跟高校信息化和数字化校园建设的步伐,利用三维激光扫描技术和VR-Platform设计,实现三维校园虚拟漫游系统。运用三维激光扫描技术采集校园主要建筑点云,用3ds Max建立校园建筑三维模型,以卫星地图截取校园地图为背景制作校园地形、道路、辅助设施、树木花草三维模型,合并简化三维模型、材质贴图、灯光布置、烘焙后将模型导入VR-Platform;制作导航图、架设多台相机、设置碰撞检测、添加骨骼角色、嵌入多媒体;通过键盘、鼠标和距离触发查看校园介绍等内容,实现虚拟场景的人机交互控制。结果表明:通过这种方法建立的虚拟校园场景逼真,沉浸感强,可多角度全方位自由漫游,在校园处突等方面能发挥一定的作用。In order to keep up with the pace of the construction of the university informatization and the digital campus, design and the virtual campus roaming system . are designed realized with the 3D laser scanning technology and VR- Platform,three dimensional laser scanning technology are used tocollect the main constructions points of the campus, and 3ds Max is used to establish three-dimensional model of the campus building. Intercepting the campus map from the satellite map as background the authors make the campus terrain, roads and other auxiliary facilities, trees, flowers and plants of 3d model, and merge and simplify those 3d models. After texture mapping, lighting arrangmant, baking and so on,then the model is imported into VR-Platform; As design navigation map, we set up multiple camera, collision detection, add bone role, embed multimedia; Users can also click on the keyboard, mouse and distance to view the campus introduction and so on, hence human-computer interactive control of virtual scene is realized. Experiment result showed ： the virtual campus scene is realistic and immersive, Users can freely roam from multiple angles. This system can play a certain role in campus emergencies.
