Description:
The study of the health of a building connects humanistic and scientific research, and a
complete characterization can be achieved by integrating all the available historical documentation,
architectural and metrological studies, as well as laboratory and in situ analyses
of the materials. A contactless, non-invasive surveying technique such as terrestrial laser
scanning (TLS) allows the acquisition of dense and accurate geometric and radiometric
(electromagnetic measurements such as signal intensity) information about the observed
surface of the building, which can be easily integrated with data provided by high-resolution
digital imaging. The early Christian Cantalovo church was surveyed for the first time in April
2011, by means of the ILRIS-3D ER very long range scanner. The second and last survey was
performed in June 2012, after the main shocks of the Emilia earthquake seismic sequence. A
very long range instrument is suitable for fast, simple and independent measurements, due to
its technical characteristics and, for this reason, is easily usable for accurate surveying in
emergency conditions. The main results are obtained by applying a data analysis strategy
based on the creation of TLS-based morphological maps computed as point-to-primitive
differences, which allow the creation of a deformation map and its evolution in time.
