航测外业控制测量是为内业加密、测图提供准确、完整、清晰的像片控制点成图资料,以保证成图的质量。但是每个像对都要在野外测求四地面控制点,造成外业工作量太大,效率不高。根据像控点的布设要求和其他有关规定,通过对外业布点方案的分析、计算,在满足内业测图精度的情况下,调整外业布点方案,大量减少外业控制测量的工作量,保证内业在加密作业时可以求得测图所需的全部绝对定向或对点纠正所需的控制点的平面位置和高程。

On the field work of aerial surveying, control surveying offers some mapping data of photograph's control points which are accurate, complete and clear to satisfy the quality of map. However, this method demands lots of work and is of low efficiency. Ac- cording to the analysis and calculation of point setting, the aerial surveying could be adjusted to decrease the workload and at the same time guarantees the needed planimetric position and elevation.
