介绍了全最小二乘法的原理,并通过实例阐述了以点到直线距离平方和最小为条件的空间直线拟合方法,同时,比较了三坐标测量对两平面平行度全最小二乘法与最小二乘法的精度,说明这种方法适用于三坐标机测量后的计算.

This article describes theory of the orthogonal least square method. The space linear fit method is introduced via numerical example, which is on the condition of minimization of the squaresum of the point to line distance. The precision of the two methods are compared in 3 dimensional coordinate measure, which indicates that the orthogonal least square method is suitable for 3 dimensional coordinate measure machine.
