摘　　要：主要阐述了基于航空摄影测量内业所采集的三维DLG数据批量获取建筑物高度的新方法,重点说明了基于城市测绘院现有的航空摄影测量有关数据和外业采集的纹理资料进行三维建模的生产工艺和流程控制。In this paper, the process flow of three-dimensional modeling, based on aerial photography 3D acquisition data, is introduced, and the new method of acquiring building height, based on largescale 3D DLG, is studied. According to the process flow above,large-area construction of 3D urban model is solved properly, and the 3 D model has high precision, satisfing the precision requeirement of 3D model totally.
