摘要: A new displacement measurement technique is proposed in a stereovision setup, which uses the object of interest as support correlation process. This procedure leads to global approach stereocorrelation. The method presented its general formulation and then particularized case non uniform rational B-splines (NURBS). field directly measured 3D expressed NURBS basis consistent with existing geometric model. kinematic measurements are validated against prescribed displacements machined Bezier patch. feasibility an industrial context shown analysis fields 2- m2 automotive roof panel during welding operation.
