物体色度值的计算机模拟表征

Chromaticity simulation using software program

本文以国际标准CIE(国际照明委员会)所规定的XYZ空间体系为基础,结合计算机计算的方法,通过利用光栅光谱仪所测的透射光谱来计算出准确的颜色,并可直接在计算机屏幕上将颜色表达出来,最后结合例子给出实验结果和相应的理论分析,结果表明:实验结果和理论分析的符合是相当好的.

Chromaticity measurement is an interdisciplin subjust and is very complex. Color of objects could be measured accurately by using computer software with the transmission spectra of grating spectrometer on the basis of the international standard, CIE XYZ system. The colors can display directly on the computer screen. The experimental results and theoretical analysis are presented in agreement also in this paper.
