摘要
提出一种评定最小二乘球的优化算法，其基本思想是利用最小二乘球线性简化模型的迭代运算去逼近最小二乘球非线性精确模型的优化解。算法具有收敛速度快、寻优精度高的优点，适用于球、半球和球冠的参数拟合及其形状误差的评定。
An optimum algorithm for fitting leastsquare sphere is presented in this paper.The algorithm is based on a kind of linear iterative calculation of an approbatory leastsquare sphere fitting model.The linear iterative calculation can approach to the optimization of the precise leastsquare sphere fitting model speedily. Therefore,the calculating precision is high and the speed rises.
