摘　　要：利用遥感影像成像时的空间投影模型并顾及全球DEM建立了一组虚拟的三维控制点,用于求解RPC模型,解决了控制点数量严重不足时RPC模型的求解问题。试验证明该方法理论严密、精度较高。In this paper, for calculating RPC model we establish a set of virtual three-dimensional GCP by using space projection model of remote sensing and global DEM, this method have more efficient to calculate RPC model when the remote sensing images don＇ t have rigorous sensor model and less ground reference point. Through the experiment shows that the method is of strictness theory and has good accuracy.

关 键 词：空间投影理论 全球DEM 三维控制点 RPC模型
