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

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。

Based on the field experiments and demonstration of key instrument and equipment for deep exploration,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 ＋ data are carried out by HIS image fusion. The results show that structural features,namely spatial distribution characteristics,between remote sensing image and gravity anomaly are different. Furthermore,the inversed geological information 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.
