High energy consumption in the construction sector largely contributes to anthropogenic climate changes. To effectively confront this concern, thermal cameras are often used to detect insulation deficiencies. However, current ground-level thermography practices do not offer a comprehensive view of the buildings. Additionally, the manual ground-level approach is expensive and time consuming. The aim of this research is to implement a more scalable approach combining an Unmanned Aerial Vehicle (UAV) with a thermal camera for building inspections. To efficiently detect areas of heat loss in buildings, a thermal and co aligned RGB imaging system for UAVs has been developed during this study. Feasibility of the whole system is evaluated within. It further investigates the quality of acquired radiometric data and opportunities for 3D thermal model generation. Results show that quality of thermal data depends on the camera’s viewing angle, which could be improved with this highly maneuverable UAV system.
