This paper investigates the use of drones for live inspection in the  construction industry. The key technical challenge is the real-time  registration of the drone video feed to the architectural plan. We  present and evaluate three different approaches for registration and  propose an edge-based prototype using visual features. Our evaluations  show that GPS alone is not sufficient for accurate registration, but  with visual features, accuracies within ten centimeters can be achieved.
