On the right are the seated audience of Hitchin Hackspace members watching as Leon Xavier, on the left, explains how to scan an object. He is scanning a full size Dalek prop using a hand held scanning head unit. The unit is like an open sphere made of triangular sections linked with thin metal tubes. A bit smaller than a football. Each node where the triangles meet has a flat disk with reflective spots around the circumference and a spot in the centre of the flat top. This contains the laser scanner head. The reflective spots are monitored by a dual camera head to track the hand unit in 3d space. The hand unit is used to "paint" the scan target with the scanning laser pattern to read the object in to the computer.
