8.1 Appendix 1 – Weighted least squares method
The principle is to associate the nominal surface with the real surface with the available degrees of freedom by minimizing , the sum of the squares of the deviations ei of the points Mi of the real surface from the associated nominal surface, with a weighting according to the area ai of the facet around the point Mi calculated, for example, using a Voronoi-type cut (figure 47...
