摘　　要：空中三角测量是航空摄影测量成图的基础环节,其质量直接影响到后期DOM、DEM及DLG的成图精度。本文结合全数字空三所涉及的影响成果精度的关键环节,从航摄影像质量、像控点测量及布设方式、区域网平差方法、平差中相关参数权值设置、作业员技术水平和态度等方面进行详细分析;提出空三质量控制方法及相关内容,从而为实际生产质量控制提供参考。Aero triangulation is a basic link of aerophotogrammetry mapping. The results directly affect the accuracy of DOM, DEM and DLG mapping. In this article, the key links of aero triangulation that affect the precision of results was analyst in detail, such as the quality of aerophotography, the layout of ground control point and surveying, the adjustment method of regional aero triangulation, the related parameter weights set for aero triangulation adjustment, the job skills and attitudes of operators. Finally the aero triangula- tion quality control standards and related content was proposed in order to provide reference for the actual production quality control.
