“…Using phase-shift TLS (in opposition to the time-of-flight TLS), it is possible to obtain data at a high speed of over 2 million points/s, which allows for a relatively fast measurement. Apart from the RGB camera, the scanners can have additional sensors, such as an IR camera, which can also be used for documentation [34]. While surveying, it is worth collecting data at the same time using several sensors (point clod, RGB image and thermal image).…”

Remote measurement of historic buildings and structures using the technology of terrestrial laser scanning (TLS) is becoming a more and more popular approach for conducting inventory activities, documentation and conservation works. In this paper, TLS was harnessed for analysis of historic brickwork structures from the 19th century. During the research programme, chosen brickwork heritage buildings were scanned. Based on the collected geometric data of the point cloud, it was possible to create an exact model of the scanned objects. The obtained radiometric information of the point cloud allowed us to identify changes in the surface of walls, such as cavities, cracks and previous repairs. Moisture was also identified in some cases. The conducted tests enabled the identification of brickwork in need of urgent repair. It was possible to assess the general technical state of the tested structures. The possibilities and limitations of the TLS diagnostic methodology of analysing the quality of historic brickwork and its future possible applications were indicated.

3D Data Fusion for Historical Analyses of Heritage Buildings Using Thermal Images: The Palacio de Colomina as a Case Study

In the framework of built heritage monitoring techniques, a prominent position is occupied by thermography, which represents an efficient and non-invasive solution for these kinds of investigations, allowing the identification of phenomena detectable only in the non-visible range of the electromagnetic spectrum. This is of extreme interest, especially considering the possibility of integrating the radiometric information with the 3D models achievable from laser scanning or photogrammetric techniques, characterised by a high spatial resolution. This paper aims to illustrate how combining different geomatics techniques (in particular, by merging thermal images, laser scanning point clouds, and traditional visible colour photogrammetric data) can efficiently support historical analyses for studying heritage buildings. Additionally, a strategy for generating HBIM models starting from the integration of 3D thermal investigations and historical sources is proposed, concerning both the multi-temporal modification of the volumes of the building and the individual architectural elements. The case study analysed for the current research was the Palacio de Colomina in Valencia, Spain, a noble palace—now the headquarters of a university—that, during the last few centuries, has been subjected to considerable transformations in terms of rehabilitation works and modification of its volume.

“…The integration between terrestrial and drone based thermography allows the multiscale observation of the building to be investigated and the map of external and internal surfaces, providing useful information not only to characterize the effects but also to identify the causes of humidity [4][5][6][7][8][9][10][11][12][13].…”

Humidity is one of the most frequent causes of damage to the architectural heritage. An effective and non-invasive way to detect the presence of humidity and identify the possible causes, from capillary rise to infiltration and condensation, is infrared thermography. The paper shows and describes the results from terrestrial and UAV-based (Unmanned Aerial Vehicle) thermography for understanding the cause-effect mechanisms of infiltration humidity in some halls of the castle of Calvello (in Basilicata), some of them characterized by walls paintings. The analysis of the acquired data allowed us to understand the nature of the damage caused by humidity and water infiltration in the castle structures, and to be able to put in place a plan for risk mitigation and damage resolution.
