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 accessing a calibration model for a camera rig. The method includes accessing multiple observations of an environment captured by the camera rig from multiple poses in the environment. The method includes generating an environmental model including geometry of the environment based on at least the observations, the poses, and the calibration model. The method includes determining, for one or more of the poses, one or more predicted observations of the environment based on the environmental model and the poses. The method includes comparing the predicted observations to the observations corresponding to the poses from which the predicted observations were determined. The method includes revising the calibration model based on the comparison. The method includes revising the environmental model based on at least a set of observations of the environment and the revised calibration model.
