Combining Reality Capture and Augmented Reality to Visualise Subsurface Utilities in the Field

In this paper, Reality Capture technologies are used to reconstruct 3D models of utility excavation holes which can later be visualised in the field, allowing for a more reliable, comprehensive and perceptible documentation and viewing of utilities before excavating to potentially reduce subsurface utility damages. An Augmented Reality (AR) prototype solution was developed and demonstrated for a group of respondents, concluding that visualising reality capturing models in AR would benefit fieldwork before, during and after excavation.
