The archaeological survey is one of the main tools for interpreting and reconstructing structures of the past. The purpose is to gain knowledge of the material civilization of the ancient world. It is particularly important for the analysis, study and reconstruction of architectural monuments.
Today, laser scanner technology is the most innovative, fastest system and it offers utmost precision in surveying objects and surfaces of any complexity and size. The individual scans, interconnected in space by means unique, mutually shared points, make it possible to obtain a digital model that corresponds to reality, a model consisting of millions of 3D points and having millimetric precision. To date, it is the most reliable method for obtaining, with utmost accuracy, 3D documentation and all sorts of measurements in the fields of architecture, engineering, archaeology and industry.
In the architectural field, it enables surveys of highly complex architectures while, in the engineering field, it is used to survey roads, bridges and tunnels, and to monitor buildings and the ground over time (landslides, excavations, volumes in general, etc.). For these areas, the key characteristics of this technique are its utmost precision, extremely high degree of detail, its ability to analyse individual surfaces and obtain a myriad of information and in any lighting.
