摘要
通过采集9种常见伪装材料及背景的光谱,进行基于反射率光谱的伪装材料的光谱分析和提取工作,然后对原始反射率光谱曲线和经包络线去除法变换后的曲线进行分析,并利用多种光谱差异算法对光谱数据进行计算,进而对伪装效果进行评估。通过实验得到了在可见光图像上难以区分的几组伪装目标的光谱特征差异,对伪装检测的波段选取及伪装材料的选择提供了参考依据。
Herein,we collected the spectra of nine types of common camouflage materials and backgrounds to analyze and extract the spectra of camouflage materials based on reflectance spectra.Then,after envelope removal,we analyzed the original reflectance curves and the spectral curves and used several spectral difference algorithms to calculate the spectral data and then evaluate the camouflage effect.Differences in the spectral characteristics of several groups of camouflage targets,which are difficult to distinguish in visible images,are obtained via experiments,thus providing a basis for selecting bands and camouflage materials.
