Using the simulated harmonic curve of profile as reference to determine and re-move the ambiguous points on the profile;
以切向廊线的拟合简谐曲线为参照，消除廓线上的模糊点；
The method uses the DC component and the first harmonic of a curve'S chain code expressed by fourier series to fit the curve, avoiding the inverse calculation of an array used in general methods.
该方法利用闭合曲线的傅立叶级数表示的直流分量和一次分量实现对闭合曲线的椭圆拟合，可以避免通常椭圆拟合方法中的矩阵求逆问题。
