Least squares fitting of spheres and ellipsoids using not orthogonal distances (English)
0 references
The author obtains estimates of the parameters of a sphere or an ellipsoid represented by the canonical parametric forms when the measured data points \((x_k,y_k,z_k)\) in space are given and also associated with measured angles \((u_k,v_k)\), \(k=1,\dots,n > 8.\) Numerical examples are given and generalizations are discussed.
