摘要

LCD是一种常见的显示设备。由于色彩空间对器件的依赖性，有必要对LCD进行表征。本文采用多项式回归的方法，建立LCD色度表征从RGB到CIEXYZ的颜色转换模型，并加入黑点校正，求解不同的多项式参数，比较色差。在实验中，选取17组训练样本求解参数，并随机选取200组测试样本验证模型的准确性。实验结果表明，三次多项式曲线模型精度最高，最大色差为4.2962，显示效果较好。

Comparative study on colorimetric characterization of LCD based on polynomial

LCD is a common display device. Due to the device dependence in color space, it is necessary to characterize LCD. In this paper, polynomial regression method is used to establish the color conversion model from RGB to CIEXYZ for colorimetric characterization of LCD, and black point correction is added to solve different polynomial parameters and compare the color difference. In the experiment, 17 groups of training samples were selected to solve the parameters and 200 groups of random test samples were used to verify the accuracy of the model. The experimental results show that the cubic polynomial curve model has the highest accuracy and the maximum chromatic aberration is 4.2962, which achieves better display effect.
