| Summary: | TLS (Terrestrial Laser Scanners) data today represents one of the most attractive ways to face the metric survey of an architectural
object. When a restoration project is needed not many restorers are used to managing 3D models and traditional graphic results such
as plans and sections are usually required. The paper defines a correct balance between the use of traditional (manual and total
station) and TLS techniques in order to satisfy the usual requirements for the metric survey of an architectural object in order to
obtain a complete 2D documentation of the San Giovanni Church in Saluzzo (Cn)– Italy that would be used for the restoration both
of the decorative apparatus and of the structure of the church. Furthermore using the acquired 3D data some tests on commercial and
open-source software for 3D modeling purpose are realised.<br><br>
The paper deals first of all with the followed methodology for the 2D documentation starting from 3D data. Moreover an analysis
and a comparison between different software packages for the 3D modeling phase is reported. |
