GPS在航空摄影辅助空中三角测量中的运用初探

The Application of GPS in the Aerial Photography Auxiliary Aerial Triangulation

传统航空摄影测量都需要使用野外控制点并通过空三加密求解像片的外方位元素。但是野外控制点测量工作量巨大、野外作业成本高,在很大程度上加大了航空摄影测量的难度。能否减少或摆脱航空摄影测量对野外控制点的依赖,已经成为航空摄影测量领域的热点课题。随着全球定位系统(GPS)的不断成熟,不仅免除了航空摄影测量中野外控制点的测量,也提高了航空摄影测量的效率与经济效益。

Abstract： The traditional aerial survey control points you need to use the wild and through the empty three encryption to solve the ex- terior orientation elements of the picture. But the wild huge workload and high cost of field operation control point measurement, to a large extent, increased the difficulty of the aerial survey. Can reduce or get rid of the aerial survey dependence on field control point, has become a hot topic in the field of aerial survey. As the global positioning system （GPS） matures, not only from the aerial survey in field control points of measurement, and improve the efficiency of aerial survey and economic benefits. Next, this article will be to the GPS in the aerial photography auxiliary discussion of the practical application of aerial triangulation.
