评估/件从散乱点椭圆 [英] Evaluating/Fitting an ellipse from scattered points

问题描述

下面是处理。我有多个点（X，Y），其形成一个椭圆像'形状

Here is the deal. I have multiple points (X,Y) that form an 'ellipse like' shape.

我想评估/适应最好的椭圆可能，并得到其属性（A，B，F1，F2），或椭圆形的，坐落在市中心。

I would like to evaluate/fit the 'best' ellipse possible and get its properties (a,b,F1,F2), or just the center of the ellipse.

任何想法/线索将AP preciated。

Any ideas/leads would be appreciated.

吉拉德。

推荐答案

有一个MATLAB函数 fit_ellipse < /一>，可以做的工作。还有本文对正交距离椭圆拟合方法。网上搜索的正交的椭圆拟合的可能会带来很多其他的资源。

There's a Matlab function fit_ellipse that can do the job. There's also this paper on methods for orthogonal distance fitting of ellipses. A web search for orthogonal ellipse fit will probably turn up a lot of other resources as well.
