摘要
3维仿真和虚拟现实技术是目前可视化研究的热门领域之一,本文选取南京大学鼓楼校区为研究对象,集成机载式和地基固定式激光雷达(LiDAR)作为建筑物3维建模基准,辅以航空遥感影像、地形底图CAD图件等多源数据实现校园场景的多层次精准表达。同时,通过3维虚拟平台和可视化编程工具整合各类地物模型,实现3维虚拟校园可视化发布。该研究技术路线3维虚拟实现效果良好,对于虚拟现实应用研究具有一定的参考价值。
Three-Dimensional simulation technology and Virtual Reality technique have become one popular research area at home and abroad.The paper taken Gulou campus of Nanjing University as virtual space,mainly discusses how to construct 3D scene of campus.It uses varieties of data sources,such as ground LiDAR of some buildings which obtain by three-dimensional laser scanner,airborne LiDAR,orthophoto and CAD base map.The 3D models of Nanjing University are integration in 3D virtual platform and implement a series of custom function by visual programming tools to provide more interaction experience.The system has a very well real time interactivity and scalability,which can be taken as a useful reference to virtual reality and digital earth development.
