基于控制点影像库纠正国产卫星影像精度研究

Accuracy Study on the Correction of Domestic Satellite Image Based on the Control Point Image Database

随着国产卫星的广泛应用,快速、高精度的纠正其影像一直是研究的重点。本文基于控制点影像库,利用中国测绘科学研究院研发的"遥感影像几何纠正子系统"对国产卫星影像进行纠正,针对其纠正结果,利用控制点影像精度评价、线划图套合等方式进行精度分析研究。

Along with the wide application of domestic satellite, fast and highly precise correction of images has been the focus of re- search. This paper, based on the control point image database, uses ＂ remote sensing image geometric correction subsystem＂ of China＇ scientific research institute to correct domestic satellite images. According to the corrected results, the paper uses the control point image accuracy evaluation and line -row- figure suit to undertake precision analysis research.
