油脂颜色测定的研究

STUDY ON THE DETERMINATION OF OIL COLOR

应用计算机图像处理技术研究罗维朋标准色片与油脂颜色的关系,得到特征参数A(R-G)和B(R/G).固定罗维朋黄色片70时,最佳特征参数为B,其他情况下最佳特征参数为A.实验得出利用A或B计算罗维朋红值的经验方程,验证结果表明,不同油脂测定罗维朋红值与计算结果的相关系数大于0.98,平均误差小于0.4.

The interrelations of lovibond standard color with oil color were studied by picture technology, two characteristic parameters A （R - G） and B （R/G） were analyzed. The optimum characteristic parameter was B when the lovibond yellow was 70, it was A in other situations. A empircal equation for the calculating of the lovibond＇ s red value with A or B. The results showed that the correlation coefficient between the results calculated with the equation and surveying lovibond values was more than 0.95 and average error was less than 0.4.
