It was possible to verify that the range maps generated by a 3D camera based on optical triangulation have the necessary resolution to show dimensional variations in the order of a few tenths of a millimeter. 3D models generated before and after the parameter variation were processed with a specific software in order to highlight the amount of deformation through a color coded image.

Abstract

This paper shows the applicability of non-contact 3D imaging technology to the dimensional monitoring of wooden artworks. The results of a study on a wooden test artifact submitted to sudden environmental parameters changes (temperature and humidity) are presented. It was possible to verify that the range maps generated by a 3D camera based on optical triangulation have the necessary resolution to show dimensional variations in the order of a few tenths of a millimeter. 3D models generated before and after the parameter variation were processed with a specific software in order to highlight the amount of deformation through a color coded image. The results demonstrate that such technique represents a unique instrument to capture and track the deformations of wooden artifacts before they become permanent. This study has been conducted in collaboration with the laboratories for restoration of the "Opificio delle Pietre Dure" at Florence, Italy
