A DIY project for building a scanner. The ingredients that make up the scanner are a webcam, some Lego bricks and milk. Milk? What does milk have to do with the scanner here?
Lets look at how it’s built. The Lego bricks used to hold a webcam. The webcam is positioned to look down on a plastic box, where the object to be scanned is placed. And milk is used to fill up the plastic box slowly in order to provide the object a high-contrast background.
The webcam tracks the changing outline of the object from above as it is slowly covered with milk. The series of outlines are layered together by software to produce a 3D model. Neat idea? I suggest to build a Lego NXT Robot to automatically pour the milk into the plastic box, which makes it more convenient to use.
