估计GM(1,1)模型中的参数通常采用最小二乘准则，而在模型精度检验时又常采用平均相对误差。
Estimation of GM (1, 1) model parameter usually adopts the least square criterion, but test of model precision often USES average relative error criterion.
通过对一自由曲面分块测量及数据拼接实验表明，这种方法参数求解简单，空间距离拼接相对误差优于0.56%。
Through an experiment for free-form surface measurement, the approach is proven to be simple for parameter computation and its relative error for space length measurement is better than 0.56%.
