A system and method can support image based determination of mobile device location through recognition of surface features for a previously scanned physical environment. The system and method can also support authoring and positioning of augmented reality features in an authoring interface using the same images and positions of surface features that are to be used for subsequent mobile device localization. As a result, mobile devices leveraging those same images and positions of surface features for localization will be more likely to obtain a localization that is consistent with the positioning displayed in the authoring interface. Augmented reality features authored using the same scan of the environment can be reliably displayed to an end user of an augmented reality application in a position consistent with their authoring in a common coordinate system, even though the authoring may have been performed remotely, away from the actual situs of the physical environment.

Machine vision determination of location based on recognized surface features and use thereof to support augmented reality

Augmented reality (AR) or virtual reality (VR) systems described herein can be configured to record images, video, and/or annotations for concurrent communication to a remote system for display or subsequent access. A communication between a user and an expert user using the system can include an audio communication (unidirectional or bidirectional), a video communication from the user to the expert user (allowing the expert user to see, in real time, the same environment as the user), and a data communication (via which content overlaid over the video communication, such as annotations, may be displayed for both the expert user and the user). The systems can be configured to communicate concurrently while also creating a recording for later review based on a 'live' or current issue being faced by a user assisted by an expert where the communication session is recorded for later playback by other users.
