【摘要】：鉴于遥感器姿态数据的准确性对影像几何定位的重要性,该文对Landsat-8卫星成像过程中,姿态抖动对多光谱影像配准的影响进行评价和分析。首先介绍了美国地质调查局(USGS)对Landsat-8卫星姿态抖动处理方法;其次,从Landsat-8陆地成像仪(OLI)的多光谱影像入手,基于蒙特卡洛数值模拟及Landsat-8真实影像,定量分析了姿态数据高频抖动对Landsat-8OLI数据波段间配准造成的误差;最后,通过模拟改变卫星姿态测量频率,进一步分析卫星抖动处理在不同频率时对抖动误差去除的适应性。Landsat-8卫星姿态抖动配准精度评估及处理方法的适应性分析,可为提高国产卫星姿态抖动处理能力及多光谱影像配准精度提供有益借鉴。
[Abstract]:In view of the importance of the accuracy of attitude data of remote sensor to image geometric location, this paper evaluates and analyzes the effect of attitude jitter on multi-spectral image registration in Landsat-8 satellite imaging process. Firstly, the method of attitude jitter processing for Landsat-8 satellite by USGS is introduced. Secondly, based on Monte Carlo numerical simulation and Landsat-8 real image, the multispectral image of Landsat-8 land imager is introduced. The error caused by the high frequency jitter of attitude data to the registration of Landsat-8OLI data band is analyzed quantitatively. Finally, the satellite attitude measurement frequency is changed by simulation. This paper further analyzes the adaptability of satellite jitter processing to the removal of jitter error at different frequencies. Landsat-8 satellite attitude jitter registration accuracy evaluation and processing methods are analyzed. It can provide useful reference for improving the processing ability of attitude jitter and the registration accuracy of multi-spectral images.
