摘要
本文介绍了相似变换和一元线性回归分析原理,用一元线性回归模型对不同平面直角坐标系之间相似变换的外推精度进行了估算。用实例验证了估算的精度,在实际应用中具有很好的现实意义。
This paper introduced the principle of similarity transformation and single variable linear regression model, a single variable linear regression model was used for extrapolate precision estimation of similarity transformation between plane right-angled nate systems. Finally, it validated the precision estimation which had strong practical meaning with the practice application, and some examples were given.
