浅谈提高空中三角测量数据成果质量的3个关键环节

Discussing the 3 Key Links to Improve the Quality of Aerial Triangulation Results

空中三角测量数据主要是为摄影测量提供定向框架数据,其质量决定最终产品的质量。笔者结合生产实践中遇到的实际问题,对提高空中三角测量数据成果质量的3个关键环节——航外控制测量,航内控制点量测,外业控制点的残差分析、空中三角测量成果检查及评定的重要性进行了阐述。

The aerial triangulation data is used to provide orientation framework data for photogrammetry. Thus the quality of aerial triangulation data impacts the quality of final products. Combing the actual problem confronted in the production practice, the authors discussed the 3 key links to improve the quality of aerial triangulation results, including field control surveying, indoor control points measurement, and the residual error analysis of field control points and the inspection and assessment of aerial triangulation results.
