摘要
物体的反射光谱数据能够反映其表面情况和光谱吸收特性,利用该数据可辨别人眼难以直观发现和识别的伪装目标,并定量表示不同的目标船只与海洋背景的差异。从色度学角度出发,提出了基于颜色和光谱特性的两个特征评价参数,即色差和光谱匹配系数,以这两个评价参数作为评价伪装系统效能的参考指标,对目标船只和我国东海南部海域的海洋背景进行相应的颜色特征提取,并分析比较目标船只与海洋背景的反射光谱分布,对目标进行伪装效果评估。结果表明,通过景物的反射光谱数据,以色差和光谱匹配系数为评价指标,为海面船只隐身效果评估提供了新的技术途径。同时,初步提出了目标识别概率公式,给出了相应的实验结果,为更加准确的隐身效果定量评价提供了参考。
The surface condition and spectral absorption characteristics of objects can be accurately reflected by their spectral reflectance data. The information of spectral distribution distinguishes the camouflaged objects which are difficult to be found and identified by human eyes, and measures the difference between a target and the background quantitatively. According to colorimetry, there are two characteristic parameters, color difference and spectral matching coefficient. Using these two evaluation parameters as reference indices, we extracted color characteristics of the target ship and the south of the East China Sea, analyzed their spectral reflectance distribution, and evaluated the effectiveness of the camouflage system. Meanwhile, we proposed the probability formula of target recognition for more effective evaluation of ship camouflage effect and obtained corresponding experiment results. The results show that the color difference and spectral matching coefficient can be used as evaluation parameters for evaluating the camouflage effect of target ships effectively.
