摘　　要：随着空中三角测量技术的不断发展,常规航空摄影测量中的外业控制测量任务虽然工作量大大减少,但它仍是加密以及后期4D产品生产的关键。本文用真实的项目数据进行实验,探索通过内业布网进一步减少外业控制测量工作量的可行性,分析得出像控点选取时所依据的原则和布设网型时可遵循的特点,以期为进一步合理减少外业控制测量工作量提供参考。With the continuous development of aerial triangulation technology,although the workload of the field control measurement in conventional aerial photogrammetry is greatly reduced,it is still the key to aerial triangulation and the production of late4D products.This paper uses real project data to experiment,to explore the feasibility of further reducing the field control measurement workload through the industry designed network,and analyzes some of the principles based on the selection of control points and the characteristics that can be followed when designing the control network,so as to provide a reference for further reasonable reduction of field control and measurement workload..
