Monitoring of oil paintings by means of optical 3D scanning

Abstract

A novel technique of monitoring of painted surfaces is proposed. Experimental results concerned with use of optical 3D scanning for monitoring of oil paintings are presented. One of oil paintings with collection of The Military-Historical Museum of Artillery, Engineer and Signal Corps (St. Petersburg, Russia) was scanned by means of optical 3D scanner, which operates using structured light. The scanning was carried out 2 times with time interval of 4.5 years. In both cases we created computing 3D models of the same painting. These models were compared using software GeomagicStudio that allowed to get a precise quantified information about deformations of canvas and frame of painting.
