直线度双节距法测量数据模型的建立和分析

Establishment and Analysis of Bi-pitch Measurement Model in Straightness

由于在直线度误差测量过程中的各种原因 ,导致许多观测数据与实际值偏离或者很难进行处理。文中介绍一种简单的处理原始实验数据的数学方法 ,即采用最小二乘理论对所测数据进行最优估计 ,来寻求最佳解。

Because of many reasons in the course of straightness error measuring, many original observed data deviate from actual value and are difficult to process. In order to seek optimal solution, a simple mathematical method to process observed data with the adoption of least square theory is described.
