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,解决了严格成像模型未知或过于复杂难以建立,同时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。A set of virtual three-dimensional GCP for calculating the RPC model is established in this paper by using the space projection model of remote sensing and global DEM, consequently the unknown of strict imaging model or excessive complexity in establishing the model are solved, and the computing problem of the RPC model is overcome when images of remote sensing do not have rigorous sensor model and insufficient ground reference points. Results of the experiments show that the theory of this method is strict, and higher precision can be provided.
