Tower of Pisa interior mapped in 3D
Researchers have used a hand-held spring-mounted laser scanner to build a 3D map of the interior of the leaning Tower of Pisa.
The data could be used by local conservators and for future interactive displays.
Here, Jonathan Roberts of CSIRO computational informatics, part of the Australian national science agency, shows how the 'Zebedee' scanner works.
While Franco Tecchia, an assistant professor at Sant'Anna School of Advanced Studies in Pisa, explains how the data could be used for future virtual displays.
