Laser Rangefinder (image) Princeton University, Engineering School Caption A team of Princeton computer scientists has developed an automated system for reconstructing an excavated fresco, mosaic or similar archaeological object. Collaborating closely with archaeologists in Greece, the team has created a system that employs a combination of powerful computer algorithms and a processing system mirroring the procedures traditionally followed at excavation sites. Here, a fragment is placed on a turntable and a laser rangefinder measures its visible surface from various viewpoints.
