[3D Scan and Print] Paintings!
I made a super-high resolution 3-D scanner for paintings. With that, we scanned two paintings by Rembrandts and a Van Gogh. In order to visualize the result, these were 3-D printed in full color and full dimension!
Paintings are not unlike sculptures, paint as a material has a huge impact on the way a painting looks. By illuminating a painting with light, it automatically gives highlights and shadows that form the way we see it. This is especially the case in the of late Rembrandt paintings and Van Gogh. This fact is often overlooked or not fully appreciated. In order to capture this topography convincingly, we needed to capture it in a very high resolution, which is already a problem for most 3-D scanners. Furthermore, the topography of the paint is very small compared to the size of the canvas and we want to capture color at the same time as we capture depth. This depth data is relevant for conservators and restorers (think of status-reports or analytical information about the craquela) and could in principle be used for exploitation using the museum shops (note that we as a university do not pursue this).
The scanning equipment is actually very straightforward, and only consists out of these parts. The rest of the parts is just cables and stuff to make the camera move in X and Y.

Real all about our scanning method in my thesis: http://repository.tudelft.nl/search/ir/?q=zaman .
We used a hybrid system using stereo vision (2 camera’s) and fringe projection (using a projector). This system gives us unrivaled detail and capture speed, capturing 40 million points per capture, each point in 3-D space (XYZ) and in full color (RGB). Multiple captures allows us to capture the Jewish Bride for instance, a work that spans 160×120 cm; giving us more than a billion XYZ/RGB points. This is all done with proprietary camera’s that anyone can buy off-the shelf.
