Discuss “New scanning technology unearths history of graves ”

When Yang Cai trekked the rocky trails of the Val Camonica Valley in the lower Alpine regions of Lombardy, Italy, he set the stage for a groundbreaking discovery in the field of 3-D image reconstruction.

Cai, director of the Ambient Intelligence Lab at Carnegie Mellon’s CyLab, became interested in 3-D imaging technology for rock art on stones this summer when he participated in the Rock Art Archeology Field in Val Camonica Valley.

Upon his return to Pittsburgh, Cai developed a unique scanning system by combining multiple, specialized components of hardware and software that examine surfaces in 3D format for various kinds of tracings. The 3-D scanning system consists of a line pattern projector, a digital camera, and 3-D image reconstruction...
