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.
