摘要

说明了HRIS相邻光谱通道图像数据具有高度的相关性

提出了基于这种特性和数据插值的畸变像元相关校正方法

该方法分为两个步骤

第一步

利用图像相关性对图像中的畸变像元进行检测

目的在于减小图像数据的变化

减少运算时间；第二步

通过曲面拟合方法

对检测出的畸变像元强度进行校正。实验表明该校正方法

具有很好的效果

并应用到了实际的HRIS数据处理中。

Abstract

It proves that adjacent band HRIS images have strong cross correlation

and presents a correlation correcting method by applying this characteristic and interpolation method. The correlation correcting method includes two steps

the first is detecting distorted pixels by using correlation

it’s purpose is to reduce images change and time cost; the second is utilizing surface fitting method to correct distorted pixels. Experiments have proved the method has a good effect

and its has been applied in practical data processing in HRIS.
