摘要
为进一步证明基于资源一号02E卫星生产的数字正射影像数据产品对测绘地理信息尤其实景三维建设应用的适用性,本文基于25景资源一号02E星影像开展数字正射影像生产试验,对比分析数据在平地、丘陵地、山地、高山地等不同地形类别的数字正射影像上采集检查点的中误差,进行卫星影像的平面几何精度检测,并与其他类型卫星影像数据进行对比和定性分析.试验结果表明,纠正后影像成果满足1∶25000比例尺制图的平面精度要求.
Abstract
In order to further prove the applicability of the digital orthophotos produced by ZY1-02E satellite images for surveying and mapping geographic information,especially for realistic 3D construction,this paper carried out the digital orthophotos production ex-periment based on 25 ZY1-02E satellite images. The planimetric geometric accuracy of the satellite images was verified by mean square errors of the checkpoints on the digital orthophotos collected from different terrain types,such as flat land,hilly land,moun-tainous land and high mountain,and the comparison and qualitative analysis were carried out with other types of satellite images. The results show that the rectified image results meet the planimetric accuracy requirements of 1∶25000 scale topographic map.
