Title (EN) MAP SUMMARIZATION AND LOCALIZATION
(FR) RÉCAPITULATION ET LOCALISATION DE CARTE
Abstract:
(EN) An electronic device [100] generates a summary map [265] of a scene based on data representative of objects having a high utility [245] for identifying the scene when estimating a current pose [275] of the electronic device and localizes the estimated current pose with respect to the summary map. The electronic device identifies scenes based on groups of objects [215] appearing together in consistent configurations over time, and identifies utility weights for objects appearing in scenes, wherein the utility weights indicate a predicted likelihood that the corresponding object will be persistently identifiable by the electronic device in the environment over time and are based at least in part on verification by one or more mobile devices. The electronic device generates a summary map of each scene based on data representative of objects having utility weights above a threshold.
(FR) Un dispositif électronique [100] génère une carte récapitulative [265] d'une scène sur la base de données représentatives d'objets ayant une utilité élevée [245] pour identifier la scène lors de l'estimation d'une pose actuelle [275] du dispositif électronique et localise la pose actuelle estimée par rapport à la carte récapitulative. Le dispositif électronique identifie des scènes sur la base de groupes d'objets [215] apparaissant ensemble dans des configurations cohérentes dans le temps, et identifie des poids utilitaires pour des objets apparaissant dans des scènes, les poids utilitaires indiquant une probabilité prédite que l'objet correspondant sera identifiable de manière persistante par le dispositif électronique dans l'environnement dans le temps et étant basés au moins en partie sur la vérification effectuée par un ou plusieurs dispositifs mobiles. Le dispositif électronique génère une carte récapitulative de chaque scène sur la base de données représentatives d'objets ayant des poids utilitaires au-dessus d'un seuil.
