Thermal photogrammetry in use for cultural heritage in the city of Varna, Bulgaria

Summary/Abstract: The case study demonstrates the two methods of thermal photogrammetry, developed by Architectural Spies EOOD for producing 3D models via volumetrizing two-dimensional thermal vision scans. Both methods were tested at the cultural heritage building at 25 Dragoman St in Varna. The first method is manual, which uses the thermal component of the scans as input data and places them onto the 3D model of the building, which could be either BIM or photogrammetrically created. In this case study BIM was used. The second method is automated, using the photo and thermal components of the FLIR scans simultaneously.
