Fitting a circle to points
WebJun 24, 2013 · You can either use a general minimization algorithm such as Levenberg-Marquardt or turn it into a linear problem and just solve for the parameters of the circle (x,y, radius). See this link for more information. I'm not aware of any multivaraible Levenberg-Marquardt for .NET so the second solution is probably easier to go for. WebJul 5, 2024 · to construct a circle out of the center points of other circles (or any elements which return a point like a sphere), select them all in the explorer and then RMB -> select all points of element. Red crosses will appear on the circle's centers. Then go to construct -> circle -> fitting circle in the menu.
