REVIEW OF GEOMETRIC AND RADIOMETRIC ANALYSES OF PAINTINGS

摘要

This paper presents an overview of a number of diagnostic campaigns carried out to assess the conservation state of paintings. The specific characteristics required in cultural heritage applications have been investigated and are reported, where two main fields are considered: radiometric analyses using multispectral images and 3D surveying for geometric deformation analysis by means of photogrammetry and laser scanning. The activities described were accomplished in interdisciplinary teams, composed of photogrammetrists, art-historians, restorers and experts of nondestructive diagnostic techniques.
