在分析三维查找表算法基本原理的基础上，采用Matlab编程建立了RGB到XYZ颜色空间的转换模型，并实验比较了4种插值算法的模型精度。研究结果表明：转换模型的转换精度较高，效果理想，且随着RGB颜色空间被划分的越细小，转换精度会越高。

The fundamental of three-dimensional look-up table algorithms was analyzed. The conversion model from RGB to XYZ color space was established by Matlab and experiments were carried out to compare the accuracy of the four algorithms. The results showed that the model has high precision and good effect; conversion accuracy can be further improved by finer division of RGB color space.
