Il rilievo digitale: il caso di studio di Palazzo Ciampoli (Taormina-Messina)

For over a decade, a new technology is emerging in the survey instrumental field, which combines the use of laser and scanner. The 3D laser scanning technology has revolutionized traditional methods of detection, enriching the field of technical design with the new digital surveyors. It allows, in fact, to acquire digitally investigated objects, automatically, non-invasive, creating a virtual model that can be interrogated at any time during post-processing. The acquisition of clouds composed of millions of points, three-dimensional data (cartesian coordinates) and colorimetric information obtained with very high precision and in a much shorter time than in the past, has led numerous research bodies, and not only, to adopt land-based measures laser scanner (TLS). The use of new techniques of digital relief is of specific scientific, methodological interest, in relation to artefacts investigated and also treated according to classical techniques. In this context, the present work concerns one of the last measurements made with TLS, under the scientific supervision of the late prof. Mario Manganaro, linked to a medieval palace located in Taormina (ME): Palazzo Ciampoli. Since September 2013, the building has undergone the recent restoration works of the Superintendency of BB.CC:AA. of Messina, which provides for the re-functionalization in an ethno-anthropological museum, in the project. In 2006, as part of a thesis, it had already been noted in a traditional way. Already at the time, the historical-architectural importance of the listed building had raised many questions about its secular stratification, which remained unanswered. The restoration work has given new attention to the building, prompting us to delve into some peculiarities of the medieval features.
