“…Specifically, ground-penetrating radar (GPR) and Infrared Thermography (IRT) were utilized in the Katholikon for the non-destructive evaluation of the pathology of the monument [58][59][60]. GPR is an established NDT for Cultural Heritage applications, as it can reveal the internal structure and assess the types and extent of structural damage of historic buildings [18,20,28,29,[60][61][62][63][64][65][66][67][68][69][70]. It exploits the propagation, diffusion, absorption, and reflection behavior of electromagnetic pulses, that are emitted from the surface of the examined area (masonry), due to the different dielectric properties of the building materials of the prospected structure.…”

“…Two-dimensional sections (b-scans) were processed with MALÅ Geoscience RadExplorer v.1.41 software. Infrared Thermography (IRT) is another established NDT that can provide valuable information regarding the materials and their decay products, the thermohygric behavior of the examined structure, and the observed pathology [18,29,[68][69][70][71][72][73][74][75]. It is based on the detection and mapping of thermal variations at IR wavelengths over the examined surfaces due to the different emissivities of materials.…”

The restoration of historic buildings and structures involves a wide range of scientific and technical fields. The grouting process is among an array of rehabilitation and preservation interventions and aims to homogenize the structure after the implementation of strengthening measures. The process can provide important information regarding the state of preservation of the examined structure and correlate the progress of the process with the pathology of the monument. To achieve this, the analysis of typical raw grouting data is progressively fused with additional information from the diagnostic studies, non-destructive testing, geospatial information, and from the calculation and analysis of grouting indices. The restoration project of the Katholikon of the Monastery of Panagia Varnakova in Fokida, Greece was selected as the case study, due to its large scale and the severe earthquake damage it has sustained, which has necessitated comprehensive strengthening interventions and extensive grouting. The implementation of an integrated methodological approach validated the enhanced level of co-analysis, revealing information that is not readily deduced from a typical approach. Selected sub-areas of the Katholikon are presented, demonstrating how the observed pathology can be correlated with the results of the grouting process, while incorporating 3D data, and findings from structural and non-destructive analyses.

“…A DEM is a raster image obtained by the projection of a point cloud onto a plane along the orthogonal direction. It is also known as a 2.5D model because it consists of a regular grid of pixels (XY), whose size is the DEM resolution, with altimetric information (Z) expressed in a colour scale [50]. We generated the Digital Elevation Models (0.14 Mpx, 1.97 mm/px resolution) from the dense point clouds using the open source CloudCompare software and imported them into QGIS software (v.3.34.5, https://www.qgis.org/it/site/, accessed on 12 December 2023), where contour lines (or isohypses, i.e., curves connecting points with the same elevation) were extracted with a 2 mm interval.…”

The 3D digital reproduction of panel paintings is an efficient practice through which to document their state of conservation thanks to the ability to study artwork both at the microscopic level, visualising the craquelure and the detachments of pictorial layers, and at the macroscopic level, analysing support structures and their deformations. In recent years, research has focused on new methodologies to handle multiple 3D scans acquired over time and to achieve data fusion to obtain multi-resolution products. In this paper, we present the results of the acquisition of the central panel of an earthquake-damaged triptych using two different 3D techniques (close-range photogrammetry and structured light) before and after its restoration to carry out a multi-temporal analysis of the conservation status and document the effects of the restoration. Furthermore, we performed laser scanning micro-profilometry on a small area of the painting to study the artist’s technique and identify previous restorations. Finally, we merged the two 3D datasets (obtained by structured-light projection and micro-profilometry) to produce a multi-resolution 3D model with the aim of increasing the accuracy and readability of the final product.
