Abstract

3D laser scanner technology, joining precision and versatility, assures survey's high quality and working time's optimization. Nowadays, this is the most advanced methodology to document, monitor and diagnose buildings which are difficult to survey for their articulated formal-geometric shape, unfavorable logistic and environment conditions. Thanks to its peculiarities, this methodology has great potentialities in archaeological survey, not yet explored; whereas traditional systems have more difficulties and limits. The aim of the present essay is to verify laser scanner's potentialities in surveying the so called “Terme dell'Indirizzo”, an organism of great interest for its spatial complexity and the substantial integrity's conditions of its ten rooms. The use of a high precision technology instrument, capable of providing great number of information (total cloud of approximately 24 million points) supported by suitable softwares, allows to realize the whole building's three-dimensional model by assembling single scansions into one reference system. The possibility of exploring the object's spatiality and of studying the three-dimensional model through several scales of detail has represented the first step for choosing the following suitable elaborations: extracting plans, prospects, profiles and sections at different heights and in appropriate parts of the model; turning the discreet model (cloud points) into a continuous one; projecting the photographic image on the mesh model in order to acquire material and pathology's information. The high precision of the analyses carried out has been the basis to undertake the subsequent critical researches in order to recognize potential modular matrices by using the ancient unit of measure (roman foot); to interpret the geometry of some complex rooms such as the Calidarium, presenting an octagonal plan covered by a dome vault; to formulate hypothesis about historical stratification, ruines and modifications occurred throughout the centuries.
