【摘要】 针对吉林一号01A星卫星影像数据的几何校正方法从模型选择、重采样方法、不同分辨率DEM数据的影响3个方面进行研究讨论。在校正模型方面,使用多项式模型、RST仿射变换模型以及RPC有理函数模型3种模型;在重采样方法上,选择了双线性内插法、最邻近像元重采样法以及双三次卷积重采样法;最后使用两种不同的DEM数据对遥感影像进行几何校正。针对这3个方面分别进行精度评定,表明RPC有理函数模型、最邻近像元重采样法、ASTER GDEM的组合是一个较好的选择。更多还原

【Abstract】 This paper studies and discusses the geometric rectification method of Jilin-1 01 A satellite image data from three aspects:model selection,resampling method and DEM data of different resolutions. In terms of calibration model,polynomial model,RST affine transformation model and RPC rational function model are used. In the resampling method,bilinear interpolation method,nearest pixel resampling method and double cubic convolution resampling method are selected. Then two different DEM data are used for geometric correction of remote sensing images. The precision evaluation of these three aspects shows that the combination of RPC rational function model,nearest pixel resampling method and ASTER GDEM is a good choice.更多还原
