A brand new app, developed by the Computer vision and geometry Lab of the Swiss Federal Institute of Technology in Zurick (ETHZ), is set to bring 3D scanning to the masses. With this new app any mobile phone could easily be turned into a 3D scanner. In other words: instead of taking a regular picture, users can now make a 3D photos with their phone.
Everything you need to do is pick out an interesting object and move your phone around it. A 3D scanned image will appear on the screen. If you keep on moving your phone after the model appears, additional images will be recorded and added to your 3D model. The app also gives its users immediate feedback when some viewpoints are missed, so users can cover those points. This is possible, because all calculations are made directly on the mobile phone.
The app works in a wide variety of settings, and it doesn’t matter whether the room is bright or dark. Therefore, you can perfectly use the app in a museum to 3D scan a statue in order to study the object at home or create your own 3D print of the statue. For instance, if you see an object you would like to have a copy of yourself, you can just scan it with your mobile phone and get it printed by a 3D printer. It’s exactly what ETHZ is doing in the following video:
