Digital Unwrapping ed visualization of complex architectural surfaces for the documentation and the restoration

Mirco Cannella

Abstract


This research explains the methodology applied to the representation of the column shafts and capitals of the Temple C in the Selinunte Archaeological Site.
Using mathematical auxiliary surfaces and NURBS modelling tools, textured highly-detailed meshes, produced with photogrammetry and laser scanner 3D data, was unwrapped onto a reference plane.
The purpose of this unwrapping is to realize orthoimages that accurately describe the conic and toric surfaces of column shafts and echinus.
Methodology gives a solution to the restoration and conservation specialists offering drawings on which to detect, map and quantify in these the damaged areas on complex curved surfaces.

Keywords


unwrapping; polygonal models; photogrammetry; laser scanning.
