Matlab在盾构隧道拟合圆测量中的应用

Application of Matlab in Measurement of Fitting Circle of Shield Tunnel

介绍了一种基于最小二乘法拟合圆函数和通过Matlab程序语言进行圆拟合的方法,该方法对实际盾构管片状态还原度高,拟合出的圆心半径也较为准确,为类似工程提供了参考。

A method of fitting circle function based on least square criterion and Matlab program language is introduced in this paper.The method has a high degree of restoration to the actual segment state and the fitting center radius is more accurate.It provides reference for similar projects.
