How does 3D scanning work?
3D scanners are basically like an overgrown
which spins slowly around its vertical axis. Another part of it like a scope spins around a horizontal axis driven
by internal motors and captures millions of points in three dimensions to
produce very accurate 3D models
of any object in its path and range.
This information can then be downloaded to computers and used for design purposes,
historic records and to detect wear and tear of machinery etc. Our Leica Scan Station can capture a million points
