Lis Termis Romanis e la Basiliche Patriarcjâl di Aquilee studiadis midiant lis modernis tecnichis di rilevament e di rapresentazion / The Roman Thermae and the Patriarchal Basilica of Aquileia analyzed by modern techniques of surveying and representation

The paper deals with the analysis of the Roman Thermae and of the Patriarchal Basilica of Aquileia by means of the modern techniques of laser scanning and photogrammetric surveying and of representation. As a preliminary Introduction, the noteworthy history of Aquileia is just briefly recalled, as well as that of the Great Roman Thermae, nowadays an area of archaeological excavations, and of the Patriarchal Basilica, one of the most significant monuments of Italian Romanesque architecture. The following Materials and methods chapter is focused, after the explanation of how laser scanning functions, then the various operative steps to automatically acquire independent clouds of millions of 3D points, transform them into a geo-referenced colour textured unique 3D surface, and represent it in many different digital views. Then, in the Results the practical surveying and representation application of the two Aquileia sites is shown, mentioning the full automation of the data acquisition in the field and the impressiveness of the data processing and the digital representations carried out with dedicated software. In the Discussion, the experience gained from the Aquileia cases and future projects are discussed, mainly concentrating on key-points of the level of automation attainable in the data processing.
