位置度测量最小二乘评定

Least Square Analysis for Evaluation of True Position

就测量中无中心基准和无角向要求的位置度评定问题 ,运用最小二乘法则对测量数据进行了误差分离优化评定 。

This paper gives the method to evaluate the true position for no requirements of datum and alignment,using the least square principle to separate the error from the measured data.The stability and conformability of the evaluated result for this kind of true position has been improved.
