A Concept for Reconstructing Stucco Statues from historic Sketches using
  synthetic Data only
Thomas Pöllabauer Julius Kühn
In medieval times, stuccoworkers used a red color, called sinopia, to first
create a sketch of the to-be-made statue on the wall. Today, many of these
statues are destroyed, but using the original drawings, deriving from the red
color also called sinopia, we can reconstruct how the final statue might have
looked.We propose a fully-automated approach to reconstruct a point cloud and
show preliminary results by generating a color-image, a depth-map, as well as
surface normals requiring only a single sketch, and without requiring a
collection of other, similar samples. Our proposed solution allows real-time
reconstruction on-site, for instance, within an exhibition, or to generate a
useful starting point for an expert, trying to manually reconstruct the statue,
all while using only synthetic data for training.
