Title (EN) LOCATION DETERMINATION USING LIGHT-BASED COMMUNICATIONS
(FR) DÉTERMINATION DE LOCALISATION AU MOYEN DE COMMUNICATIONS BASÉES SUR LA LUMIÈRE
Abstract:
(EN) Disclosed are methods, systems, devices, apparatus, computer-/processor- readable media, and other implementations, including a method, at a processor-based mobile device, that includes determining a first set of candidate positions of the mobile device corresponding to a first time instance based, at least in part, on position data including a first set of identifiers decoded from signals including respective first one or more light-based communications received by the mobile device from a first one or more light devices, with the mobile device being located at a first location at the first time instance. The method further includes selecting at least one candidate position from the first set of candidate positions, in response to a determination that the first set of candidate positions includes more than one candidate position, in order to resolve positional ambiguity, based, at least partly, on further position data from further signals from one or more devices.
(FR) L'invention concerne des procédés, des systèmes, des dispositifs, un appareil, des supports lisibles par ordinateur/processeur, et autres modes de réalisation, y compris un procédé, au niveau d'un dispositif mobile basé sur un processeur, qui consiste à déterminer un premier ensemble de positions candidates du dispositif mobile correspondant à un premier instant sur la base, au moins en partie, de données de position comprenant un premier ensemble d'identifiants décodés à partir des signaux comprenant une ou plusieurs premières communications basées sur la lumière respectives reçues par le dispositif mobile en provenance d'un ou de plusieurs premiers dispositifs lumineux, le dispositif mobile se trouvant à une première localisation au premier instant. Le procédé consiste en outre à sélectionner au moins une position candidate parmi le premier ensemble de positions candidates, en réponse à une détermination selon laquelle le premier ensemble de positions candidates comprend plus d'une position candidate, de manière à résoudre une ambiguïté de position, sur la base, au moins partiellement, d'autres données de position provenant d'autres signaux provenant d'un ou de plusieurs dispositifs.
