摘要
基于色温的基本理论,对三角垂足插值法、黑体轨迹的Chebyshev法、模拟黑体轨迹弧线法和M cCam y近似公式法等四种相关色温计算方法进行了比较分析。从理论和实验两方面分别讨论了各种算法的预测精度和应用特点,并给出了综合比较结果。
Based on the principle of color temperature, four typical algorithms were studied for calculating correlated color temperature （CCT）, triangle perpendicular interpolative method, plank locus Chebyshev method, plank locus arc simulating method, and McCamy＇s approximate formula. The CCT prediction accuracies and application properties of all these algorithms were discussed theoretically and experimentally in detail ,and give the result.
