摘要：Some of the results of surveys carried out at the Leaning Tower of Pisa (Italy), the ancient theatre of Taormina (Italy), the prehistoric site of Nola (Naples-Italy) are detailed in this work. The aim of the survey of the Leaning Tower of Pisa was in particular to evaluate the extent of the lean and it is the understanding of which that is essential for any consolidation work. The main goal about the survey of the theatre of Taormina has been the masonry analysis performed in few days. At the end, the survey of the prehistoric site of Nola has given a "digital preservation" of a 3.700 b.y. ancient village destroyed by Vesuvius volcanic eruption. The survey was carried out using a portable 3D laser scanning system "Cyrax 2500" which captures, visualizes and models structures with an unprecedented combination of completeness, speed and accuracy. In this survey the complete surface geometry of the exposed surfaces was remotely captured in a form of dense, accurate "3D point clouds", ready for immediate use. The next step was to draw the horizontal and vertical sections, making use of the large measurement data base that had been compiled on site. This was done utilizing dedicated modelling software
