摘要
给出了一种适用于数字闭合曲线的椭圆拟合方法。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。在对目标轮廓无先验知识的情况下，一次便可得到其拟会椭圆方程的所有参数，从而确定其方位。
his paper presents an ellipse fitting method adaptive to a closed digital curve fortarget location and tracking. 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. Without any empirical knowledge about the target profile all parameters of it's ellipse fitting function can be obtained straightforwards.
