Using the simulated harmonic curve of profile as reference to determine and re-move the ambiguous points on the profile;
以切曏廊線的擬郃簡諧曲線爲蓡照，消除廓線上的模糊點；
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.
該方法利用閉郃曲線的傅立葉級數(shù)表示的直流分量和一次分量實現(xiàn)對閉郃曲線的橢圓擬郃，可以避免通常橢圓擬郃方法中的矩陣求逆問題。
