*Well, I can’t say I’m surprised to discover this, because I’m used to the idea that I learn something new in Torino every day.
Nowadays, digital tools allow the reconstruction of no longer
visible cultural heritage based on different sources, testing
various processes for manifold purposes. The choice of which
digital techniques and strategies are the best to be applied for
the virtual reconstruction is determined by the available sources
and by the final level of detail that need to be achieved. Last but
not least, diverse objectives influence the results, but the use of
3D digital reconstruction is reported in different disciplines to
support various analysis and consideration: hypothetical
reconstruction giving life to never realized projects from
original drawings (Apollonio et al., 2017), mean to support
restoration in case of destruction (Bitelli et al., 2017),
diachronic visualization of lost constructive phases of urban
heritage and repositories of historical photos of architectures
connected to a 4D web viewer (Münster et al., 2020, Rodriguez-
Gonzálvez et al., 2019).
As regards the possible approaches, reconstruction based on old
images or frames extracted from ancient videos constitute one
possible method to extract the shape of the object; nonetheless
more than one image or more frames captured with different
point of view are necessary. Despite low resolution and lack of
camera parameters/information, images not captured with
photogrammetric requirements have been proved to be an
interesting source of information exploiting photogrammetric
data processing, especially SfM algorithms (Beltrami et al.,
2019, Maiwald et al., 2017). Despite this kind of images lacks
of metric information and the integration with measurements is
necessary, different researches combined dimensions contained
in original drawings (Condorelli, Rinaudo, 2018), coordinates
obtained with current Terrestrial Laser Scanning (TLS) or…
