Abstract
In one embodiment, techniques are provided for projecting information (e.g., describing subsurface features such as subsurface utilities) onto a surface (e.g., road surface) of the physical environment using pre-captured topography (e.g., determined by structure-from-motion (SfM) photogrammetry) and pre-projection of the information onto the pre-captured topography. The pre-projected information is subsequently combined with a live view of the physical environment to produce an augmented reality view that is displayed to a user.
