摘要
在天绘一号卫星1B级产品生产中,三线阵与高分辨率影像的像控点匹配结果直接影响着高分辨率影像的RPC精度。本文介绍了天绘一号卫星高分辨率影像1B级产品生产过程,给出像控点匹配优化策略,基于此开发了高分辨率影像匹配软件。实例说明,与原生产软件相比,该软件在匹配的可靠性和精度上有显著优势。
In the production of TH-01 satellite 1 B-level data,image control point matching results of three-line-array and high-resolution images directly affect the RPC accuracy of high-resolution images.The processing method of 1 B-level data is introduced in this paper.Based on the given optimization strategy of image control point matching,it develops a high-resolution image matching software.Compared with the original production software,the developed software is proved that has remarkable advantages in reliability and accuracy of matching.
