摘要
本文研究了椭圆曲线拟合的各种方法。从拟合质量、计算复杂度等方面,对每种拟合方法进行了分析和对比,并且分别对基于像散法的光探针式表面形貌测量系统图像中的椭圆进行曲线拟合,从中确定出最适合的拟合方法-加权新度量法。实验与仿真结果表明,用该拟合方法确定椭圆参数是可行的,逼近效果较好且具有较强的抗噪性。
This article studies different ellipse-fitting methods.In the view of fitting-quality,complexity of calculation and so on,it analyzes and compares these fitting methods.Then picks out the most favourite method-powerd new measurement method by using these methods to fit the ellipses in the images of the optic-probe surface profile measurement system.The results of experiments and emulations indicate that it is feasible to calculate the parameters of ellipse by using this ellipse-fitting method,it has good approaching effect and anti-noise capability.
