Science is no stranger to the efforts to preserve ancient wonders. Now, 3D scanners have been added to the conservation arsenal. Researchers have been using scanners to record every detail of building exteriors, but a new hand-held laser scanner is being used to build a 3D map of the interior of the Leaning Tower of Pisa.
BBC Click’s Neil Bowdler reports on how 3D scanning is helping conservation efforts for museums and institutions.
It’s not just about recording historical artefacts, visitors can now see 3D displays of exhibits that may have been lost in storage somewhere. And it’s becoming an important tool in archaeological research. 3D scanning can help look at details beneath the design, or used to create replicas, or replace damaged items by printing out artefacts.
