对引起遥感影像模糊的因素进行了分析,从光学系统、大气及传感器与地面的相对运动三方面出发,导出了遥感影像的调制传递函数,从而利用维纳滤波算法对遥感影像进行复原处理。考虑到遥感影像数据量大的问题,对图像采用分块处理的方法。实验结果表明该方法能有效的对退化的遥感影像进行复原。
This paper analyzed the factors that caused remote sensing images blurred.Analyzing optical systems,atmosphere,the relative motion between the sensor and the ground to deduce the modulation transfer function(MTF) of remote sensing images.Wiener Filters were applied to the restore remote sensing images.Given the huge volume of remote sensing image data,a partitioning method was adopted for image processing.Experiment confirmed that the proposed method can effectively restore the blurred remote sensing images.
