棉花色泽分级的研究

Research on the Classification of Cotton Color

本文以色度学原理为基础,分析了包括棉花色泽在内的颜色立体、CIE1931 XYZ色度系统光谱三刺激值与棉花色泽参数之间的关系,取得棉花体表的颜色参数,实现对棉花色泽的客观分级处理。为保证分级的正确性,还讨论了准确模拟人眼视觉色觉功能的y(λ)、z(λ)光电探测器的研制方法、照明系统设计、仪器的定标以及提高仪器测量精度的方法。

Based on colorimetry,the color solid including cotton color and the relationship between spectral tristimulus value of CIE 1931 XYZ system and the parameters of cotton color are analyzed in detail.The color parameters of cotton surface are got and the classified processing of cotton color is implemented objectively.In order to guarantee the accuracy of color classification,the photodetectors y(λ),z(λ),which are matched for simulating the human sense of sight and color,are developed.The illumination system,the method of calibration and improving the measuring; accuracy of the instrument are also discussed.
