DIGITAL ARCHIVING

The tools for digital archiving are called 3-dimensional scanners. The 3D scanners and their associated software rebuild the object from the digitized points of the 3-dimensional coordinate system. The digital model created in this way is a perfect copy of the original object and also contains the calibrated, RGB colour-coded colour data, which can also be examined separately from the 3-dimensional surface.

Contactless spatial data collection is particularly important in the area of cultural use, as the physical touch of a damaged stucco, a high-value painting, or a hundreds years old sculpture can also cause great damage. The great advantage of non-contact digitization of 3D scanners is that they create a 3-dimensional “fingerprint” of the work of art that results in “portable”, visible and well-visualized spatial data, making it easier to identify an already tested painting or sculpture whether it coincides with the 3D file or not.

3D FINGERPRINTS

Digitization of Claude Monet: Water Lilies
(Switzerland – Winthertour)

A 3-dimensional fingerprint is a procedure developed to identify paintings and sculptures, which in essence is the same as the individual fingerprints prevalent in criminal practice. The principle of the method is to record the surface of the structure as a 3-dimensional model. The digital model recorded this way is a perfect, distortion-free representation of the original object. The virtually rotatable 3-dimensional “copy” can be weighed, and the perfectly recorded colour data can be analyzed. The resolution of a digitized artifact is 5 microns, it is a fraction of a millimeter. The 3-dimensional scanning of the painting makes it possible to examine the damage and warping with the aid of computer visualization.
The 3-dimensional fingerprint can be used to verify a restoration process or to re-identify a missing artifact. Artifacts inspected by 3D digitization cannot be tampered with either, as it is immediately clear from the repeated test whether the result of the control test is the same as the originally taken “fingerprint”.
