正在成像的物体的光谱反射率的重建对于在各种观察光源下再现颜色是重要的。在这项工作中，导出了一个简单的公式来评估一组旨在重建光谱反射率的彩色图像传感器的质量，并将其应用于多光谱图像采集系统。由于质量不仅取决于光谱灵敏度，还取决于系统中存在的噪声，所以不可能在没有其中存在噪声的情况下对一组传感器进行评估。因此，多光谱相机的噪声方差由新方案估算，并首次应用于评估。结果表明，实验结果与评估模型的预测吻合良好，估计噪声方差估计方法对评估是有用的。(The reconstruction of spectral reflectances of objects being imaged is important in reproducing a color under a variety of viewing illuminants. In this work, a simple formula is derived to evaluate the quality of a set of color image sensors aimed at reconstruction of spectral reflectances, and it is applied to multispectral image acquisition systems. Since the quality depends not only on the spectral sensitivities but also on the noise present in the systems, it is impossible to evaluate a set of sensors without prior knowledge of the noise present in it. Therefore, the noise variance of the multispectral cameras is estimated by a new proposal, and it is applied to the evaluation for the first time. It is shown that the experimental results agree well with the predictions by the evaluation model, and that the method to estimate the noise variance is useful for the evaluation.)
