多源遥感影像融合的基本原理和实现方法

为满足遥感影像处理的实际需要,需要将单一传感器或不同类别传感器获取的多源遥感影像信息进行综合,提高遥感影像的利用效益。本文以SPOT与TM影像的融合为例,探讨如何将高分辨率全色影像与多光谱影像融合从而获取更有利于进行地物判别的、兼具高空间分辨率与多光谱信息特性的影像的原理与方法。

The Fusion Algorithms of Multi-source Remote Sensing Images

To solve the practical problems and improve the utilization of remote sensing images,we should integrate the information from the images which are scanned from a single sensor or multiple sensors.In this text,I will use the fusion algorithms of SPOT images and TM images as a example to analyse the principle and the inplement of the panchromatic images and multi-spectral images＇ fusion in which condition both TM ′s spectrum and SPOT＇s resolution will be best used.
