Fitting of circular curve based on least square method and iterative method

CHEN Mingjing;FANG Yuanmin;CHEN Jie;Faculty of Land Resource Engineering,Kunming University of Science and Technology;  
In order to improve the accuracy of circular curve fitting in deformation monitoring,the paper proposed a fitting method of circular curve based on least square method:under the criterion that the sum of the squares of the geometric distance difference between the original radius and the fitting radius is minimum,combined with iterative method in the calculation process,the fitting precision could be improve effectively in the case of non-uniform collecting for discrete points.Finally the result of processing test data proved the feasibility of the fitting method.
