基于稀少控制IKONOS的近海岸岛礁立体影像定向研究

Orientation With Sparse GCPs Based on IKONO SHRS Images of Inshore Island and Reef

针对我国岛礁控制现状,进行了基于稀少控制IKONOS的近海岸岛礁立体影像区域网平差定向实验,通过对不同控制方案的定向精度分析,提出了稀少控制的岛礁影像控制点布设方案,为我国近、远海重点岛礁的立体影像定向测图提供参考。

This paper analyzed the ground control points situation of island and reef, and performed the orientation experiment of inshore IKONOS HRS Image using Block Adjustment with sparse GCPs. Through analyzing the different adjustment precisions, proposed control setting methods with sparse GCPs of island and reef image and provided the references for surveying the key islands and reefs which are near or far away form the continents.
