摘　　要：绿色颜料常被用于丛林伪装中,本文通过2种光谱相似度评价方法比较了铬绿、碱性品绿、茜素绿、铁绿、蓝色(钴蓝、群青、磺化酞菁钴、酞菁蓝、铁蓝)与黄色颜料(铋黄、铁黄)混合物等10种常用的绿色系颜料与植物叶片的相似度。其中铬绿颜料与植物叶片的相似度最高,分波段相似度均较好。通过光谱一阶微分法对颜料种类进行区分,与植物相似度高的铬绿颜料可通过光谱识别指数方法加以识别。光谱识别指数方法可以快速地提取目标信息,大大提高识别的速度。Green pigments are often used in jungle camouflage.This article compares the similarity between 10 commonly used green pigments and plant leaves,including chromium green,alkaline magenta green,alizarin green,iron green,blue pigments(cobalt blue,ultramarine,cobalt sulfonated phthalocyanine,phthalocyanine blue,iron blue),and yellow pigments(bismuth yellow,iron yellow)mixtures,using two spectral similarity evaluation methods.Among them,the similarity between chrome green pigment and plant leaves is the highest,and the similarity in sub bands is good.The types of pigments are distinguished by the first order differential method of spectroscopy,and chromium green pigments with high similarity to plants can be identified by the spectral recognition index method.The spectral recognition index method can quickly extract target information,greatly improving the recognition speed.
