摘　　要：为充分利用高光谱成像技术提供的丰富的光谱信息和纹理信息,对光学伪装效果进行综合评价,提出了一种结合光谱曲线形状相似度、光谱欧氏距离以及纹理欧氏距离的伪装效果综合评价方法。利用绝对关联度、欧氏距离和灰度共生矩阵分别对三类特征进行量化,从形状测度和距离测度两方面综合考量光谱信息和空间纹理信息,求得综合测度。该方法在理论上更加缜密,实验表明综合测度有较好的稳健性,避免了单一测度的不确定性,对伪装器材的设计和使用具有指导作用。To fully utilize abundant spectral and texture information in hyperspectra, a method to comprehensively evaluate the optical camouflage effect is proposed. The method combines the similarity of spectral curve shape, the spectral Euclid distance and the texture Euclid distance. The three features are quantified by the absolute correlation degree, Euclid distance and gray level co occurrence matrix, respectively. The spectral and the texture information are taken into consideration in terms of the shape measure and the distance measure to obtain a comprehensive measure. This method is rigorous in theory, and it is experimentally proved to be robust and avoid the uncertainty of single measure. It is instructive for camouflage material design and usage.
