摘要
在对高分辨率影像进行几何纠正、影像拼接以及制作正射影像图的基础上,制作了某实验区的三维地形景观,并利用SketchUp进行地物的精细建模同时通过ArcGIS 9.3进行三维显示和三维系统的二次开发。实验结果表明:利用高分辨率影像制作的三维地形具有地形逼真、清晰度高、信息量丰富等特点;完成了ArcGIS与三维建模软件的数据交换以及所建立模型的查询功能。
In this paper,Produced a three-dimensional Terrain Landscapes of the experimental area based on geometric correction,image stitching and the production of Orthophoto of High resolution images.using sketchup make the fine model of ground objects,and using ArcGIS 9.3 make 3D display and the secondary development of 3D systems.The experimental results of new 3D visualization in front show that 3D terrain of High resolution images have the characteristics of realistic terrain and high-definitiondetailed and rich information;At last Completed the three-dimensional modeling software ArcGIS and data exchange and the establishment of the model query.
