摘要：

针对传统的人工配色繁复、效率低而现有的计算机配色修色算法不能满足生产实践需求的问题，在MatLab软件中开发出了一套计算机辅助色纺纱配色系统，并对该系统中的配色模块和修色模块进行了改进。在配色模块，采用在［0 1］区间对未知参数Ｍ值和对单色纤维初始配方赋值迭代的方法，改进了采用M 值平均数的方法以及基于最小二乘法的初始配方求解算法；在修色模块，采用单色纤维调整量中间函数差最小的方法，改进了基于最小二乘法的三刺激值或反射率修色算法。该模型经过1~2 次修色可得到色差小于1 的配色结果，能满足色纺纱生产中多组分、定比例的配色、修色基本要求。

Abstract:

Aiming at the peoblem that conventional artificial color matching is complicated, and low in efficient, and the existing computer color matching algorithm can not meet the needs of production practice. A computer-aided color matching system for colored fiber was developed in MatLab software, and the color mataching and the xolor repairing module of the system were improved. In the color matching module, the method of calculating the mean vwlue of the M value and the recipe solution based on the least squares method were improved by using the method of assignment and iteration to the unknown value M and the initial recipe of the monochromatic fiber in the [0 1] interval. In the repairing module, the tristinulus value or the reflectance color repairing algorithm based on the least squares method was improved by the method of minimizing the difference in the function of monochromatic fiber. The colord matching model can achieve the matching result with color difference smaller than 1 after reparing color for 1~2 times , which can satisfy the basic requirements of the color matching and color repairing of multi-component and fixed proportion in the production process of colored fibers yarn.
