CA 2741005
The invention relates to a method for adapting a visual representation which subsequently is subjected to a deformation, like in packaging. To be able to take into account the deformations on the visual representation the method comprises the steps of: providing a pattern on a support, wherein the pattern comprises a distribution of codes, which are arranged such that each code is unique, deforming the support with the pattern, taking at least two images of the deformed support under different points of view, and determining a 3D surface model based on the matching of at least one code of the pattern in the at least two images.
L'invention concerne un procédé permettant l'adaptation d'une représentation visuelle qui est soumise ultérieurement à une déformation, comme lors d'un conditionnement. Afin de prendre en compte les déformations de la représentation visuelle, le procédé consiste à : appliquer un motif sur un support, le motif comprenant une distribution de codes, chacun étant conçu de sorte à être unique, déformer le support comportant le motif, prendre au moins deux images du support déformé depuis plusieurs points de vue, et déterminer un modèle de surface en 3D sur la base de la mise en correspondance d'au moins un code du motif dans les deux images ou plus.
