Abstract: The disclosed computer-implemented method may include acquiring, from a client device within a real-world environment, information representative of the real-world environment, and transmitting the information representative of the real-world environment to a relocalization service. The method may further include receiving, from the relocalization service, (1) an anchor point that may include a mapped position within the real-world environment, and (2) a determined position within the real-world environment of a client device relative to the mapped position of the anchor point. The method may further include sending an identifier of the anchor point to an asset management service, and obtaining, from the asset management service, a digital asset. The method may further include presenting the digital asset at a position within an artificial environment relative to the mapped position of the anchor point. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: In one embodiment, a method includes determining correspondence data between a sequence of images based on identified features in the sequence of images and predicted pose based on motion data, and determining current state information based on the correspondence data and the motion data. The current state information comprises at least a current pose of the wearable device relative to the environment capture by the one or more cameras. Furthermore, the method comprises receiving map points in a three-dimensional map and their associated descriptors based on the identified features in the sequence of images and identifying one or more of the map points in the sequence of images based on the associated descriptors associated with the map points. The current state information is further determined based on the identified one or more of the map points.
