基于Skyline Terrasuite的城市三维景观的建立

Establishment of 3D Urban Landscape Model Based on Skyline Terrasuite

以东北大学彩色航空摄影像片和大比例尺地形图为数据源,利用VirtuoZoNT3.5获得DOM数据和DEM数据并进行预处理,使其拥有相同的坐标系统;利用三维地理信息系统软件SkylineTerrasuite将DOM叠加到DEM上构建三维表面来表示三维场景和建筑物的屋顶纹理;利用数码相机对建筑物的侧面纹理进行采集,对建筑物的结构框架进行纹理映射,实现城市三维景观的可视化。

This paper takes the color photography picture and large-scale terrain map from Northeast University as data source,and gains the DOM data and DEM by using VirtuoZoNT3.5. After pretreatment, these data can have the same coordinate system. By using 3D GIS software Skyline Terrasuite, we overlay DOM to DEM structuring the vein coming to show 3D circumstances and the building roof 3D surface. Also by making use of a digital camera to collect the side vein of buildings,we can achieve 3D landscape of city Visualization. The paper discus above-mentioned method process, and give some experience summary.
