Abstract

La présente invention a trait à un procédé et un appareil destinés au paramétrage en géométrie tridimensionnelle d'une surface tridimensionnelle. Un modèle aléatoire de speckle est projeté puis représenté sur la surface afin de produire plusieurs images numériques bidimensionnelles. Les images bidimensionnelles sont traitées de façon à donner une caractérisation tridimensionnelle de la surface. La surface lumineuse peut être modélisée pour produire un ensemble de paramètres caractérisant la surface sur la base des images numériques bidimensionnelles.
