The Zebedee, created by Australia’s national space agency, is a 3-D scanner, but it’s not quite like any 3-D scanner we’ve ever seen before. But that might work in its favor: one person holding the Zebedee was able to accurately 3-D map the entire Leaning Tower of Pisa in only 20 minutes!

The Zebedee is a laser scanner, not an infrared scanner like the Kinect or most of the other 3-D scanners we come across. The laser scanner sits on a spring, bouncing comically and uncontrollably back and forth, pointing all over the place as it does. The heavy lifting of the Zebedee is done in software, as all that conflicting laser data is converted to a 3-D map.

It’s actually a subtly genius idea; most 3-D scanners are fixed, requiring human intervention to make sure they point at all possible angles. But the Zebedee, through its sproinging, manages to capture everything all by itself. Sure, lots of elements will be scanned multiple times–but that’s not necessarily a bad thing, as long as the software is capable of sorting out the redundant data in a reasonable time-frame, which it sounds like this data is.
