基于IHS变换的重力异常与遥感影像融合的构造信息提取研究

本文以深部探测关键仪器装备野外实验与示范基地为例,利用影像融合技术进行地质构造信息的提取。在卫星遥感和重力异常数据空间配准的基础上,利用IHS数据融合方法,将重力异常与ETM+数据进行融合与分析。研究表明:一方面构造形迹在遥感图像及重力异常上的表征是存在差异性的,即其空间分布特征,另一方面通过卫星遥感在地表定位重力异常所反演的地质信息,能够为深部探测仪器装备野外实验选点提供科学的依据。

Structural information extraction based on gravity anomaly and remote sensing image fusion by IHS transformation

Based on the field experiments and demonstration of key instrument and equipment for deep explo- ration，the image fusion technology is conducted to extract geological information． Considering spatial registration of satellite remote sensing and gravity anomaly， the image fusion and analysis between gravity anomaly and ETM + da- ta are carried out by HIS image fusion． The results show that structural features，namely spatial distribution charac- teristics，between remote sensing image and gravity anomaly are different． Furthermore，the inversed geological in- formation obtained by localizing gravity anomaly from remote sensing data，provides a scientific basis for the field experimental reconnaissance by utilizing detecting instrument and equipment for deep exploration．
