摘　　要：针对大面积无人机航空摄影测量过程中,由于地形起伏等原因导致在无像控点情况下多个测区合并进行空三不能准确定向的问题,本文提出了一种以测区DEM之间的航线基准面高度差为基础,实现对无像控制点测区归并的方法。较之于传统的人工归并方法,该方法在测区匹配效率和划分准确率方面有大幅提升,这种基于DEM的倾斜摄影无像控点测区归并方法对大面积山区航空摄影数据的处理具有较强的借鉴意义和较高的应用价值。In view of the inaccurate orientation in aerial regulation of various observation areas without photo control points in the process of large-scale UAV oblique photogrammetry due to terrain fluctuation and other reasons,this paper proposes a matching method to divide different no photo control points areas on the basis of the height differences of air route datum between DEMs in contiguous observation areas.This method has a great advantage over the traditional manual matching division in efficiency and accuracy,which is referential and applicable to the data processing of large-scale aerophotography in mountainous areas.
