Towards Drone-sourced Live Video Analytics for the Construction Industry

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.
