| 摘 要： | 以数字化校园工程———“数字成都理工大学”为例,探讨利用航空影像和数字摄影测量技术,获取基础空间地理信息的方法及途径。并采用三维建模软件Cyber C ity对建筑物进行三维建模。而对于复杂地物,采用三维地理信息系统IMAGIS软件建立单个模型,从而实现了成都理工大学校区的三维可视化虚拟重建和漫游。实践证明,利用数字摄影测量技术和遥感影像,能够有效地获取大范围区域地表地物的三维信息,并快速地建立地面模型和三维景观。

| Abstract: | In this paper,the authors take the project of digital campus-"Digital Chengdu University of Technology" as an example to discuss the method and approach of acquiring basic spatial geographic information by using aerial remote sensing images and digital photogrammetry.In order to realize the three-dimensional virtual modeling and roaming of digital campus of Chengdu University of Technology,regular buildings were built by using 3D modeling software-Cyber City,and complicated objects were constructed by 3D GIS software-IMAGIS.The result shown that using remote sensing image and digital photogrammetry is not only efficient to acquire basic spatial geographic information,but also fast to build 3D scene for large area. |
