在印刷质量检测中,不同型号测量仪器测量结果差异较大。 针对这一问题,提出了一种三维空间拟合算法,建立了正反向模型,用 i1Pro 和 SpectroEye 这 2 种企业常用的测量设备互相预测,最后计算了预测值与实际测量值之间的色差。 实验结果显示,98% 的色差小于 2,表明该算法具有比较好的结果。

In print quality inspection, measuring results from different model of measuring instruments are quite different. A three-dimensional fitting algorithm was put forward to solve this problem. Forward and backward models were established. Measured value of i1Pro and SpectroEye, which were both commonly used in enterprises, were used predict each other. The color difference between the predicted value and the actual measured value was calculated. The experimental results showed that 98% of the color difference is less than 2, indicating that the algorithm has good result.
