    摘要： Systems and methods for facilitating contextual queries based on media samples automatically captured by a computing device are disclosed herein. A server receives from a computing device over a communication network, a media sample of a media asset automatically captured by the computing device. The server obtains contextual information corresponding to the captured media sample. The server stores the media sample in a memory indexed by the contextual information. The server receives, from the computing device over the communication network, a query that includes a criterion but lacks an identifier of the media asset. The server identifies the media sample in the memory by matching the query criterion to the contextual information. The server generates a reply to the query based on the identifying of the media sample and communicates the reply to the computing device over the communication network.

    摘要： A computer-implemented method includes capturing visual data of an environment using an image sensor of an electronic device and non-visual data of the environment using one or more non-image sensors of the electronic device. Feature descriptors of one or more objects in the environment are generated using the visual data of the environment and the non-visual data of the environment. A map of the environment is generated using the feature descriptors of the one or more objects. One or more virtual objects are anchored to at least one of the objects using the map. The visual data, the non-visual data, and the map are combined in a digital multimedia container file. The digital multimedia container file is stored on the electronic device or on another electronic device connected to the electronic device.

    摘要： A method and an apparatus for retrieving a 3D map are provided. The method for retrieving a 3D map includes: obtaining binary data of S 3D map descriptors; performing stage-i retrieval in the binary data of the S 3D map descriptors based on binary data of a retrieval descriptor, to obtain P 3D map descriptors through screening; performing stage-m decompression on compressed data of the P 3D map descriptors to obtain reconstructed data of the P 3D map descriptors; and performing stage-j retrieval in the reconstructed data of the P 3D map descriptors based on partial data or all data of the retrieval descriptor, to obtain Q 3D map descriptors.
