摘要
我们研制的ISI2000NV反射比/色差测量系统是兼有测量物体的光谱反射比特性及其色度特性两大功能的系统.它利用其内置的光谱仪可测得可见-近红外波段反射物体的半球空间的反射比,继而可反演出物体的色度特性.本文就后一功能在实现原理及计算方法上加以描述.
Abstract
ISI2000NV is a system for both semispherical spectral reflectance and color difference measurement. It can gives color difference of objects based on semispherical spectral reflectance in visible and near infrared wave bands measured by its internal spectrometer. The principle and method of color difference computation were investigated in detail.
