摘　　要：以崇阳县为例,介绍了利用SWDC-5AP100倾斜摄影系统获取影像数据,再生产DEM和DOM,进而对崇阳县城区进行三维建模的过程;并利用已有的DLG数据对模型进行了精度评定。结果表明,其精度均满足规定要求,倾斜摄影测量极大地提高了三维建模效率,对实现快速三维建模具有重要意义,为今后开展基于倾斜摄影的三维建模提供了可靠依据。Taking Chongyang County for example,we mainly introduced the 3D modeling process of Chongyang County by using oblique photogrammetry technique.SWDC-5AP100 oblique photogrammetry system was used to obtain image data at first.And then,DEM and DOM were produced.Finally,3D model of Chongyang County was built.In this experiment,we used the existing DLG to evaluate the accuracy of 3D models.The results show that the accuracy of 3D models can meet the requirements.Oblique photogrammetry greatly improves the efficiency of 3D modeling,which is of great significance to realize fast 3D modeling,and provides a reliable basis for 3D modeling based on oblique photogrammetry in the future.
