Software tool for drone flight management in supervising building extern façades

Objetive:The main goal is to develop a software called DroneFaçadeto manage the drone flight and generate an image mosaic of a building façade, allowing the continuous monitoring and registering the state of the façade through time.Methodology:The software DroneFaçade was developed considering three operational phases: GPS-based acquisition of waypoints, image-data acquisition flying the drone through the computed trajectory, and the offline mosaic computation. The waypoints are captured using GPS Exchange Format. Then, these waypoints are introduced into DroneFaçade, proper coverage of the façade is computed using the intrinsic camera parameters, the drone trajectory is computed, and the battery changing points are defined. Afterwards, the flight mission starts capturing image data the in the on-board Jetson-Nano development system running ROS. Next, the telemetry and image data are imported into a SQL-database system, and the mosaic computation is performed. At the end, DroneFaçade generates a report in PDF about the façade inspection.Results:To validate DronFaçade two different tests were performed: integration tests according with RUP methodology to check the functional requirements fulfillment, and a quantitative field test to check que quality of the mosaic computed. As a result of the quantitative test, the mosaic image computed by DronFaçade has low structural errors, preserves phase congruency and the magnitude of the image gradients, keeps high correlation and an appearance similarity of up 92.6% with respect to the real scene.. Conclusions:DroneFaçade is a software tool which can be an option to register through time the building façades state and performing corrective actions to avoid high building deterioration thanks to the high quality image mosaics generated.
