(FR) SYSTÈMES DE VISION ARTIFICIELLE ET PROCÉDÉS DE MODÉLISATION DE STRUCTURES TRIDIMENSIONNELLES À L'AIDE DE SEGMENTS BIDIMENSIONNELS DÉTECTÉS DANS DES IMAGES AÉRIENNES NUMÉRIQUES
Abstract:
(EN) A system for modeling a three-dimensional structure utilizing two-dimensional segments comprising a memory and a processor in communication with the memory. The processor extracts a plurality of two-dimensional segments corresponding to the three- dimensional structure from a plurality of images indicative of different views of the three- dimensional structure. The processor determines a plurality of three-dimensional candidate segments based on the extracted plurality of two-dimensional segments and adds the plurality of three-dimensional candidate segments to a three-dimensional segment cloud. The processor transforms the three-dimensional segment cloud into a wireframe indicative of the three-dimensional structure by performing a wireframe extraction process on the three-dimensional segment cloud.
(FR) La présente invention concerne un système de modélisation d'une structure tridimensionnelle utilisant des segments bidimensionnels et comprenant une mémoire et un processeur en communication avec la mémoire. Le processeur extrait une pluralité de segments bidimensionnels correspondant à la structure tridimensionnelle à partir d'une pluralité d'images indicatives de différentes vues de la structure tridimensionnelle. Le processeur détermine une pluralité de segments tridimensionnels candidats sur la base de la pluralité de segments bidimensionnels extraits et ajoute la pluralité de segments tridimensionnels candidats à un nuage de segments tridimensionnels. Le processeur transforme le nuage de segments tridimensionnels en une structure filaire indicative de la structure tridimensionnelle en réalisant un processus d'extraction d'une structure filaire sur le nuage de segments tridimensionnels.
