| 摘 要： | 针对严密的基于共线方程的正射纠正方法对IKONOS影像的不适用性，文中论述基于有理函数模型的单片环境下IKONOS影像正射纠正方法，并对基于有理函数模型的定位方法及系统误差补偿、基于空间模型的坐标转换方法、双线性内插法、灰度叠加法等关键方法进行详细说明。在此基础上，进行直接和间接两种正射纠正方法的实验研究．得到一些有益的结论。

| Abstract: | In view of the inapplicability of collinearity equation in IKONOS orthorectification,this paper discusses the method of IKONOS orthorectification in single photo environment based on rational function model and elucidates the key techniques,including the positioning theory based on rational function model and compensation for systematic error,coordinate transformation based on space model,bilinear interpolation and the resampling method of gray overlay.On this basis,experiments of direct and indirect orthorectification are carried out and some useful conclusions are drawn in the end. |
