摘　　要：稀少控制航测可以大大减少外业测绘的工作量,随着GPS辅助航测技术的发展,使稀少控制测绘成为可能。本文以国产SWDC航摄仪为研究基础,阐述了GPS辅助数码空中三角测量的原理、技术流程及具体测区稀少控制的典型航测试验。结果表明,SWDC航摄仪的航测精度满足1∶1万地形测绘需求,验证了国产SWDC实施稀少控制航测的应用可行性。The field surveying workload is sharply reduced with sparse control photogrammetry. It is possible for the realization of sparse control photogrammetry with the development of GPS aided by air survey. This paper dwells on the theory, the technology flow of GPS- aided triangulation, and classical photogrammetry test in the surveying region with sparse GCPS based on SWDC digital aerial camera. The test result shows that the surveying precision of SWDC meets the demand of the topographic survey with the scale of 1 ： 10 000. Furthermore, it is testified that the domestic SWDC is able to the application in the surveying region with sparse GCPS.
