3D Scanning for Periodical Conservation State Monitoring of Oil Paintings

3D laser and optical scanning are widely used in the engineering field to obtain digital representations of complex surfaces. Its high precision and harmless working principle make it an invaluable tool in Cultural Heritage Science. One recent application for 3D scanning is the monitoring of the conservation state of oil paintings. Two studies were carried out in 2014 and 2019 on an oil painting that is part of the collection of the Military-Historical Museum of Artillery, Engineer and Signal Corps (St. Petersburg, Russia) to evaluate its preservation progress over a period of time. In 2021 a new study was performed with a 3D structured light scanning device. The goal of this work is to show how 3D scanning can be used as a tool to continually evaluate the conservation status of this type of fine art and verify for signs of aging, comparing the obtained results in the different studies.
