高光谱遥感图像矿物填图模块设计

Design of mineral mapping module of hyper-spectral remote sensing image

针对光谱仪从野外测得的高光谱遥感数据,提出一种基于IDL的矿物组合填图模块,该模块主要利用光谱角度填图法(SAM)与光谱信息散度法(SID)对高光谱遥感图像进行矿物填图,并通过不同颜色填充能够对矿物进行区别并有选择地进行查看.

In terms of the hyper - spectral data measured by spectrometer in the field, a module of mineral mapping based on IDL was proposed, which mainly use spectral angle mapping method （SAM） and spectral information divergence method （SID） for hyperspectral remote sensing image mineral mapping, in which minerals were distinguished by color, and selectively check was obtained.
