Proportion of solid colour fibres can be exactly predicted utlizing the least square calculating method.This colour matching result is matchable to spectrum.

使用最小二乘算法可以准确的预测各单色纤维的比例，配色结果可以达到光谱匹配。

Finally experiments indicate that squared cancroid method is better, which is simple and easy implemented and improves the locating precision and the Noise resisting ability.

通过实验表明，平方加权质心法是一种较为理想的细分定位方法，不仅简单、易于实现，而且具有更高的定位精度以及抗噪声的能力。
