Abstract
A scanning device for scanning an interface surface is disclosed. The scanning device includes a beam generator for emitting a beam, a deflector for deflecting the beam to generate a raster scan pattern over a scanning patch, and a sensor for receiving a reflected beam from the scanning patch and sensing from the reflected beam data encoded by coded tags printed on an interface surface. The data encoded by each tag includes an identity of the interface surface and the position of the respective tag on the interface surface. The scanning device further includes a processor for determining a description of the interface surface from the sensed interface surface identity and at least one region of the interface surface from the determined description and the position of the sensed tag on the interface surface.
