【摘要】 介绍了摄影测量加密中两种地球曲率改正方法及其基本原理，并在摄影测量与非摄影测量观测值联合平差程序ＷｕＣＡＰＳ中予以实现。通过对某测区一组实际ＧＰＳ控制飞行的航片的处理得到，两种改正方法对常规自检校光束法平差结果没有显著影响，而在ＧＰＳ辅助光束法平差中的作用明显不同。文中对试验结果进行了分析和讨论，并提出了实用建议更多还原

【Abstract】 This paper describes two kinds of methods for correcting earth curvature in GPS supported bundle block adjustment.A set of actual aerial photos with GPS camera position data taken from Tianjin’s experimental project was used in the test,which was done by using combined bundle block adjustment program system WuCAPS.The experimental results have shown that the accuracy using strict method is much better than that using common method for GPS supported bundle block adjustment.In this paper,some useful suggestions for practical GPS supported aerotriangulation are presented.更多还原
