摘　　要：随着地理信息服务对数据更新要求越来越高,处理卫星遥感影像速度也要求越来越快。RPC无像控点校正遥感影像是目前较流行的快速遥感影像处理方式。资源三号遥感卫星是我国第一颗民用高分辨率测绘卫星,其轨道定位和相机参数精度高,可以实现较高精度的RPC影像校正。本研究通过广西多个不同地形地貌地区的资源三号卫星遥感影像的RPC校正,分析其影像绝对定位精度以及多光谱影像与全色光谱影像的相对定位精度,评估进行快速无像控点影像校正的可行性。As geographic information services have higher and higher requirements for data update,it is required to be able to quickly process satellite remote sensing images.RPC remote sensing image correction without image control points is currently the most popular fast remote sensing image processing method.The ZY-3 remote sensing satellite is my country's first civilian high-resolution surveying and mapping satellite.Its orbit positioning and camera parameters are highly accurate and can achieve high-precision RPC image correction.In this study,the RPC correction of the remote sensing images of the ZY-3 satellite in many different terrain and landforms in Guangxi was used to analyze the absolute positioning accuracy of the image and the relative positioning accuracy of the multispectral image and the panchromatic spectral image,and feasibility,evaluate the rapid image correction without image control points.
