Typical 3D object scanners have to be mounted with a tripod or mounting arm, and it’s almost impossible to scan small, enclosed spaces or objects which could not be brought to the scanner.
You can scan objects in a single pass, then download the data to your machine via a FireWire connection. You can even scan confined spaces such as the interior of an automobile or a room. You’ll still need to place reflective targets on the key vertices of objects to be scanned, but that’s par for the course for 3D scanning.
All this convenience does come at a price though. The scanner runs $39,900 USD, but if you’re a 3D imaging professional, you’ll want one of these in your bag of tricks.
