Abstract
(EN)
A system and method for automatically modeling symmetry planes and principal orientations from three dimensional ("3D") segments. The system comprises receiving a set of 3D segments representing a structure from the input source, wherein the set of 3D segments comprises one or more segment pairs. The system then generates symmetry plane data by calculating a symmetry plane for each of the one or more segment pairs. Next, the system accumulates the symmetry plane data in a Hough space. Lastly, the system constructs one or more Hough space symmetry planes from the symmetry plane data and calculates a principal orientation of the structure.

La présente invention concerne un système et un procédé pour modéliser automatiquement des plans de symétrie et des orientations principales à partir de segments tridimensionnels (« 3D »). Le système comprend la réception, au niveau d’une source d’entrée, d'un ensemble de segments 3D représentant une structure, l'ensemble de segments 3D comprenant une ou plusieurs paires de segments. Le système génère ensuite des données du plan de symétrie en calculant un plan de symétrie pour chaque paire de segments. Ensuite, le système accumule les données du plan de symétrie dans un espace de Hough. Finalement, le système construit un ou plusieurs plans de symétrie de l'espace de Hough à partir des données du plan de symétrie et calcule une orientation principale de la structure.
