Title (EN) METHODS, DEVICES AND COMPUTER PROGRAM PRODUCTS FOR 3D MAPPING AND POSE ESTIMATION OF 3D IMAGES
(FR) PROCÉDÉS, DISPOSITIFS ET PRODUITS-PROGRAMMES D'ORDINATEUR PERMETTANT UNE ESTIMATION DE CARTOGRAPHIE 3D ET DE POSES D'IMAGES 3D
Abstract:
(EN) A method for estimating a 3D map and a plurality of poses is described. The method includes non-recursively performing an initialization of the 3D map and the respective poses of the plurality of poses based on a plurality of first 2D images of the series of 2D images, and recursively performing sequential updating of the 3D map based on recursively updating the 3D map for respective ones of a plurality of second 2D images of the series of 2D images. Related systems, devices and computer program products are also described.
(FR) L'invention concerne un procédé d'estimation d'une carte 3D et d'une pluralité de poses. Le procédé comprend la réalisation non récursive d'une initialisation de la carte 3D et des poses respectives de la pluralité de poses en fonction d'une pluralité de premières images 2D de la série d'images 2D, et la réalisation récursive d'une mise à jour séquentielle de la carte 3D en fonction de la mise à jour récursive de la carte 3D pour des images respectives d'une pluralité de deuxièmes images 2D de la série d'images 2D. La présente invention concerne également des systèmes, des dispositifs et des produits-programmes d'ordinateur associés.
