中文摘要: 三维景观模型的生成是近年来GIS领域研究的一个热点问题,它可将航测数据库数据转换成可视化的三维视觉显示图像,能逼真呈现线路所经区域的地形环境,有着广泛的应用前景。基于航片利用microstation软件和ImageStation SSK获取城市三维景观建模所需的基础空间数据,并对数据进行了研究与处理,使采集的数据得到优化,发现采集中出现的错误和误差并进行改正。利用IMAGIS三维地理信息系统软件对城市已有建筑物进行建模,且应用真实照片对其进行贴面,使得效果更贴近现实。最终生成城市三维景观图像,并用3Dbr

Abstract:Generating three-dimensional landscape model is a hot topic in the field of GIS in recent years. It can convert aerial survey data into three-dimensional visual maps, which can show the terrain of the routevividly, and have broad application prospects. In this paper, basic spatial data that three-dimensional landscape modeling needed are obtained by the microstation software and ImageStation SSK based on aerial image, and the data are analysed and processed. The collected data are optimized so that the errors can be found and revised. Existing buildings in the city are modeled by using the IMAGIS 3D geographic information system software, and the application of real photos veneer them made the results closer to the reality. Finally the three-dimensional urban landscape maps are generated, and AVI video is created with 3Dbrows .
