Description
The geometrical model and the ranscac modules are very usefull to fit different object to a point cloud even in very noisy case.
However the geometrical shapes that implemented up to now are only two: Palane and Sphere.
I have implemented an ellipsoid model and its ransac version.
The fitting algorithm is the least suqares, both to fit all the points in the cloud and a subset of them.
The minimum number of non complanar points to perform the fit is 11.
