Using 3-D scanners, the institute provided all the original data needed to reproduce the cave and its carvings. For a 10-meter-tall statue, the error between the original work and the replica is less than 5 millimeters.
Such technology has been employed in other projects. For example, researchers replicated cave No 220 of the world-renowned Mogao Grottoes in Dunhuang, Gansu province. During the project, the team used newly developed equipment to record every detail of the frescoes, which date to the Tang Dynasty (618-907).
After making high-resolution images, the team used software to stitch them together into a single picture with high precision, said Diao Changyu, a computer specialist.
The technology can also help solve archaeological mysteries, researchers say. For instance, the team helped identify a badly damaged stone tablet last year after collecting 3-D images of it.
