Designed and developed by the artist Manuel Franquelo, Lucida has been
created to obtain contact-free, high-resolution 3D data out of the surface of
paintings and low-relief objects.
The system projects a thin beam of red light onto the surface of the painting.
As the beam moves across the object the distortions caused by the surface
uctuation are recorded by two video cameras positioned either side of the
laser. The video footage is archived as raw data as well as processed as a
tonal depthmap.
