基于Skyline黄河流域3维景观的建立

The Building of Yellow River Valley Three-Dimensional Landscape Based On Skyline

以ADS 40航空影像为数据源,利用Leica数字摄影测量系统制作黄河流域的正射影像及DEM;利用3维GIS软件Skyline将DOM叠加到DEM上构建3维场景;利用3DMAX进行桥梁的精细建模并进行格式转换;利用数码相机对建筑物、桥梁和堤坝的侧面纹理进行采集并进行纹理映射,实现了黄河流域3维景观的可视化。

Taking ADS 40 aerial images as data source,DOM and DEM of Yellow River valley are made by using Leica digital photogrammetric system;three-dimensional landscape is established by adding DOM to DEM using Skyline which is a 3D GIS software;bridges are subtly modeled by 3DMAX and format is converted;the side textures of buildings,bridges and dams are collected and mapped using digital camera.At last,the three-dimensional landscape is realized.
