We carried out a 3D survey of the exterior and interior of the entire complex of the Abbey of Santa Maria di Vezzolano, one of the most important examples of Romanesque-Gothic architecture in Piedmont.
The challenge
The aim of the project was to provide an accurate description of the complex in order to plan refurbishment works for improved tourist use, as well as to digitally document the altarpieces undergoing restoration. This required a highly detailed and extensive survey.
The “ad hoc” solution”
An integrated approach was used, combining various surveying techniques, including traditional topography, GNSS surveying, terrestrial and drone photogrammetry, and terrestrial laser scanning, in order to combine metric accuracy, completeness of description, and execution times in the creation of a complete colour 3D model of the site.
The result
Starting from the colour 3D digital model obtained, the documents requested by the client for design purposes were extracted: nadir orthophotos of the site, precision orthophotos of the individual facades, CAD renderings of the elevations and plans. High-resolution digital models of the altarpieces were also created, combining triangulation laser scanners with terrestrial and drone photogrammetry. The orthophotos produced were used as a basis for the restoration, including in the environment. Ad Hoc Maintenance Manager (Ad Hoc MM).
