We have collected a set of human-generated 3D models from Trimble
3DWarehouse for the following architectural landmarks: Notre
Dame of Paris, Trevi Fountain, and San Marco’s Basilica. The Trimble
3D Warehouse models for these sites consist of basic primitive
shapes and have a composite texture from a set of images. In addition
to the Trimble 3D Warehouse models, we also consider a 3D
model of San Marco’s Square that was reconstructed from a set of
photographs using dense multiview stereo [Furukawa et al. 2010].
Note that while the latter 3D model has more accurate geometry
than the Trimble 3D Warehouse models, it is also much noisier
along the model boundaries.
We have also collected from the Internet 85 historical photographs
and 252 nonphotographic depictions of the sites.We separated
the nonphotographic depictions into the following categories:
“drawings” (60 images), “engravings” (45 images), and “paintings”
(147 images). The drawings category includes color renderings and
the paintings category includes different rendering styles, such as
watercolors, oil paintings, and pastels. Table I shows the number of
images belonging to each category across the different sites
