南极地区小象幅航测内业成图

AEROPHOTOGRAMMETRIC MAPPING WITH SMALL FORMAT OF AEROPHOTOS FOR ZHONGSHAN STATION IN ANTARCTICA

本文阐述了用１２０型非量测相机对南极中山站地区所摄制的１４００００小象幅航片制作１５０００地形图、正射像片图及１１００００地形图的原理、方法和精度。在外定向中适当增加控制点及考虑到加入适当的权的情况下，其外定向最大对点误差平面为２．２ｍ，高程为１．２ｍ。所制作的正射像片图和相应的地形图套合中误差为０．１４ｍｍ。其结果完全可满足南极科研。

The principle,method and accuracy for the producing of 1∶5000 topographic map and its orthophoto as well as the 1∶10000 topogrophic map,which are based on the 120type non metric camera and the 1∶40000 small format aerophotoes of the area near Zhongshan Station in Antarctica,are discussed in this paper. In the case of increasing the number of control points properly and adding with some suitable weights during the exterior orientation procedure,the maxium point fitting errors are 2.2m in plane and 1.2m in elevation recpectively. The mean square error of fitting between the correspending topographic map and its orthophoto is 0.14mm. Above results can meet the needs of research and inspect work of the Antarctic area.
