摘要 有理函数模型(Rational Polynomial Coefficients,RPC)是一种常用的影像几何关系表达模型,可以用于精确表达所有影像的成像几何关系,正广泛地被业界所接受。本文在国产光学卫星严密成像几何模型基础上,介绍了RPC模型和无偏估计参数求解算法。利用资源一号02B星、资源二号03星数据进行实验的结果证明了方法的正确性以及RPC模型对国产卫星影像的适应性。 The RPC(Rational Polynomial Coefficients)model is a kind of universal expression model for image geometry,which can be used to express accurately all the image geometric relations and has been widely accepted by industry.Based on a description of the rigorous sensor model for domestic optical satellite imagery,this paper deals with the RPC model and unbiased estimation algorithm.Using the imagery of the domestic satellites ZY1-02B and ZY2-03,the authors have proved the correctness of the method and the adaptability of the RPC model for domestic satellite imagery.
