摘要
地物光谱是遥感技术应用与研究的物理基础。本文提出将地物在光谱特征空间的几何点阵结构特征作为研究重点,着重分析植被、土壤、岩石的野外实测光谱数据的光谱空间结构特征,并对所测得地物的光谱数据进行光谱线性混合模拟,进而分析线性混合地物的光谱空间结构特征。对实测地物光谱数据空间结构特征的分析不仅可以指导遥感影像数据的分析与应用,而且也为遥感影像地物目标识别和矿化蚀变信息提取技术的研究提供更多的科学理论依据和新的研究思路。
Object spectrum is the physical basis of application and study of the remote sensing technology.In this paper,the geometric lattice structure in the spectral feature space of object is as the focus of research.The spectral characteristics of rock,soil,vegetation and spectral hybrid simulation data are analyzed based on spectral feature space.The conclusion can guide the analysis and application of remote sensing image data,meanwhile,it provides more scientific foundation and new research approach for researchers who study on the classification or information extraction with remote sensing data.
