The experimental activities were originally planned for April and May 2020, but they had to be postponed several months because of the global pandemic situation. The on-site campaign was crucial for the project, as the first tasks required the collection of the geometrical and construction data to build the full 3D models.
During the experimental on-site campaign carried out in November 2020 at the Archaeological Museum of Carmo, ultrasonic tomography and Ground Penetrating Radar (GPR) inspection were used for the inspection of two columns to distinguish the internal boundaries between different materials and identify the stone blocks that constitute the column. The innovative automatic acoustic tomography system developed by the CSIC/UPM team has been specifically adapted to the shape of the masonry columns of the museum and was implemented for the first time.
