Abstract
(EN)
The invention relates to a method for characterising three-dimensional objects, including steps comprising: i) generating a three-dimensional reconstruction of a three-dimensional object; ii) generating a mesh of the object, said mesh being made up of points connected two-by-two by a ridge; iii) characterising the points and/or faces of the mesh of the object according to the statuses of remarkable properties at said points; iv) splitting the object into contiguous three-dimensional regions based on the mesh and the characterisation of the points thereof; v) creating a database of regions that represent objects of an environment; and/or vi) screening a region on a database in order to find objects that contain similar and/or complementary regions; and/or vii) inferring functions of the objects according to similarities in the regions thereof; and/or viii) inferring interactions between objects by complementarity of the regions thereof; and/or ix) specifying the frequency of a region in an environment.

L'invention concerne un procédé de caractérisation d'objets tridimensionnels comprenant les étapes consistant à : i) générer une reconstruction tridimensionnelle d'un objet tridimensionnel; ii) générer un maillage de l'objet, ledit maillage étant constitué de points reliés deux à deux par une arête; iii) caractériser les points et/ou facettes du maillage de l'objet en fonction d'états de propriétés remarquables en ces points; iv) segmenter l'objet en régions tridimensionnelles contigϋes à partir du maillage et de la caractérisation de ses points; v) créer une base de données de régions représentatives des objets d'un environnement; et/ou vi) cribler une région sur une base de données pour retrouver des objets portant des régions similaires et/ou complémentaires; et/ou vii) inférer des fonctions aux objets par ressemblance de leurs régions; et/ou viii) inférer des interactions entre objets par complémentarité de leurs régions; et/ou ix) préciser la fréquence d'une région dans un environnement.
