Methods, systems, and computer-readable media for reconstruction a three-dimensional scene from a collection of two-dimensional images are provided. A computerized reconstruction system executes computer vision algorithms on the collection of two-dimensional images to identify candidate planes that are used to model visual characteristics of the environment depicted in the two-dimensional images. The computer vision algorithms may minimize an energy function that represents the relationships and similarities among features of the two-dimensional images to assign pixels of the two dimensional images to planes in the three dimensional scene. The three-dimensional scene is navigable and depicts viewpoint transitions between multiple two-dimensional images.

L'invention porte sur des procédés, des systèmes et des supports lisibles par ordinateur pour reconstruction d'une scène tridimensionnelle à partir d'une collecte d'images bidimensionnelles. Un système de reconstruction informatisé exécute des algorithmes de vision d'ordinateur sur la collecte des images bidimensionnelles afin d'identifier des plans candidats qui sont utilisés pour modéliser des caractéristiques visuelles de l'environnement représenté dans les images bidimensionnelles. Les algorithmes de vision d'ordinateur peuvent minimiser une fonction d'énergie représentant les relations et les similarités parmi des caractéristiques des images bidimensionnelles de façon à attribuer des pixels des deux images bidimensionnelles à des plans dans la scène tridimensionnelle. La scène tridimensionnelle est navigable et représente des transitions de point de vision entre des images bidimensionnelles multiples.
