| 摘 要： | 传统卫星影像纠正常针对单景影像,且需要一定数量的外业控制点作为参考,严重制约了正射纠正效率。本文提出了一种卫星影像区域网平差方法,利用影像间的连接点进行RPC模型的前方交会,并用少量控制点进行仿射变换,实现了多轨多景卫星影像的区域网平差。经测试,本文方法可有效减少外业控制点,提高卫星影像正射纠正效率。

| Abstract: | Traditional single-view satellite image correction requires some field control points. This paper proposes a satellite image block adjustment method, using the connection points between the images to carry out the forward intersection of the RPC model, and using a small number of control points for affine transformation to realize satellite imagery multi-track multi-view block adjustment. After testing, it can effectively reduce the field control points and improve the ortho rectification efficiency of satellite imagery. |
