摘　　要：IMU/DGPS(惯导测量仪/差分全球定位系统)技术航测成图法可直接获取外方位元素,缩短航测成图周期,降低航测成本。通过相应的试验及具体生产的实施,阐明利用该技术获取的控制数据进行1∶50000DOM制作的技术流程及作业过程中出现问题的处理方法。The elements of exterior orientation of the aerial photos can be got directly by the aerial photogrammetry with the technology of IMU/DGPS（Inertial Measurement Unit/Differential Global Position System）.It can reduce the cost, improve the efficiency of production and shorten the production period. By the relevant test and the practical project, this paper clarified the technical flow using this technique to produce digital orthographic map of 1：50 000 scale, and the solution of the problems appeared during the process.
