| Abstract: | 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 : 10000. Furthermore, it is testified that the domestic SWDC is able to the application in the surveying region with sparse GCPS. |
