Fitting circles and lines by least squares
WebHence, the least squares flt by circles is, technically, impossible. For any circle one can flnd another circle that flts the data better. The best flt here is given by the straight line trough the data points, which yieldsF= 0. If we want the LSF to exist, we have to allow lines, as well as circles, in our model, and from now on we do this. WebWe recommend Taubin fit. Kasa fit (the simplest and fastest fit, but biased toward smaller circles when an incomplete arc is observed) Pratt fit (more robust than Kasa fit, but a little slower) Taubin fit (similar to Pratt fit, but a bit faster and a bit more accurate) (perhaps the best algebraic circle fit) Hyper fit (a new fit: a combination ...
