Abstract

Procédé de génération d'un modèle virtuel en trois dimensions d'au moins une partie d'un squelette d'un individu, caractérisé en ce qu'à l'aide d'un dispositif d'imagerie (1) on observe l'individu (Ind) et: - d'une part, on génère une pluralité de paramètres extrinsèques au squelette de l'individu et représentatifs de la géométrie d'une enveloppe externe (E) ; et - d'autre part, on génère des images radiologiques sur lesquelles sont représentées ladite au moins une partie du squelette de l'individu ; et à l'aide desdits paramètres extrinsèques, on détermine dans les images radiologiques des zones d'intérêt à observer, puis on recherche dans ces zones d'intérêt des points caractéristiques d'os du squelette pour en déduire des positions relatives de ces os dans un référentiel spatial et ainsi générer ledit modèle virtuel en trois dimensions de ladite partie du squelette de l'individu.Method for generating a virtual three-dimensional model of at least part of a skeleton of an individual, characterized in that, using an imaging device (1), the individual is observed (Ind) and: - on the one hand, a plurality of parameters extrinsic to the skeleton of the individual and representative of the geometry of an external envelope (E) is generated; and - on the other hand, radiological images are generated on which said at least part of the skeleton of the individual is represented; and with the aid of said extrinsic parameters, in the radiological images areas of interest to be observed are determined, then in these areas of interest characteristic points of skeletal bones are sought in order to deduce therefrom the relative positions of these bones in a spatial frame of reference and thus generate said virtual three-dimensional model of said part of the skeleton of the individual.
