摘要
空间遥感成像时,为提高图像信噪比,串行扫描方法得到广泛运用。设计了特殊排列的光纤束,利用该光纤束耦合的扫描成像系统,通过控制扫描步进长度,让目标依次通过每层光纤束,获取多幅数字图像。将多幅数字图像还原目标图像时,借助模拟积分的概念,提出了简单平均、选择平均和加权平均三种处理方法,更加有效地提取了图像特征和消除脉冲干扰。
A scanning image system with fiber bundles coupling, could get several images at one time by controlling the scan step to let the image of same object go through the fiber bundles one by one. Comparing to analog integral, three different methods-simple average, selecting average and coefficient average were introduced to process these digital images to restore the original object image. It is effective to extract the feature of image and eliminate pulse noises
