摘要
为解决国产资源02C卫星影像相机内方位几何标定问题,提出了一种利用公众地理信息数据进行高精度相机内方位在轨几何标定的方法。该方法利用资源02C卫星影像与公众地理信息数据自动配准获取的海量地面控制点并进行附加自检校参数的最小二乘平差,实现了资源一号02C卫星P/MS相机的内方位标定,精度可以达到子像素级。
This paper proposes a novel method for the on-orbit interior orientation parameters (IOP) calibration of ZY-I 02C panehromatic/multispectral (P/MS)camera based on the qualified public GIS data. Auto-matching 02C satellite images and GIS data obtains numerous control points to perform the /east square adjustment with additional parameters. After the IOP geometric calibration, the interior accuracy of the images is improved to sub-pixel levels.
