Augmentation of Road Surfaces with Subsurface Utility Model Projections

Subsurface utility work planning would benefit from augmented reality. Unfortunately, the exact pipe location is rarely known, which produces unreliable augmentations. We proposed an augmentation technique that drapes 2D pipe maps onto the road surface and aligns them with corresponding features in the physical world using a pre-captured 3D mesh. Resulting augmentations are more likely to be displayed at the true pipe locations.
