    摘要： The present disclosure provides systems and methods that makes use of one or more image sensors of a device to provide users with information relating to nearby points of interest. The image sensors may be used to detect features and/or objects in the field of view of the image sensors. Pose data, including a location and orientation of the device is then determined based on the one or more detected features and/or objects. A plurality of points of interest that are within a geographical area that is dependent on the pose data are then determined. The determination may, for instance, be made by querying a mapping database for points of interest that are known to be located within a particular distance of the location of the user. The device then provides information to the user indicating one or more of the plurality of points of interest.

    摘要： L'invention concerne un procédé de communication de données représentatives d'une information spatialement localisée à un terminal mobile (1) en fonction de la localisation dudit terminal mobile (1) dans une surface de vente munie d'une série d'étiquettes électroniques répartie, chaque étiquette électronique (3) comprenant un module de communication radiofréquence (32), une mémoire (33), un écran d'affichage (31) et un microcontrôleur (34), le procédé comprenant les étapes suivantes :
    - le terminal mobile (1) établit une communication par radiofréquence avec un périphérique radiofréquence d'une étiquette électronique (3),
    - le périphérique radiofréquence (36) communique audit terminal mobile (1) un identifiant d'étiquette de ladite étiquette électronique (3),
    - le terminal mobile (1) communique ledit identifiant d'étiquette à un serveur central (2),
    - le serveur central (2) détermine une localisation dudit terminal mobile (1),
    - le serveur central (2) communique au terminal mobile (1) des données représentatives d'une information spatialement localisée.

    摘要： The present application discloses a query method, an apparatus, an electronic device, and a storage medium, and relates to the technical field of spatio-temporal big data in big data technologies. The specific implementation scheme is as follows: receiving a query request sent by a terminal device, where the query request is used to request to query dynamic association relationships of a target entity and includes an identifier of the target entity and query starting and ending time; determining at least one time bucket to be queried in a query database according to the query starting and ending time, where each time bucket stores the dynamic association relationships of the target entity in a time period corresponding to the time bucket; and querying the dynamic association relationships of the target entity in the at least one time bucket according to the identifier of the target entity. Compared with the prior art, the present application uses a time bucketing method to query dynamic association information of the target entity, which allows for effectively reducing the calculation burden and improving the speed for querying the dynamic association information.
