Geo-augmented field excursion for geological sites

摘要

Systems and methods include a computer-implemented method for annotating an augmented reality display. An indication that a user is present at a digital stop in a geographical region is received by an augmented reality (AR) device. 3D annotation information associated with a 3D location of the AR device in a 3D reconstructed map of the real world is received. A virtual reality display that overlays, in real-time, the 3D annotation information onto real-world objects in the geographical region is provided. A location of the AR device is determined and tracked using a six degrees-of-freedom localization system. A visual view of the AR device is associated with a pre-acquired 3D point-based model. Features of real-world objects are annotated. Simultaneous localization and mapping of the AR device and the visual view are performed to annotate 3D features during movement of the AR device. Features of the real-world objects are annotated.
