Patent ID: 8493628

Claim:
A system configured to reproduce a two dimensional image onto a surface, comprising: a three-dimensional model containing a feature to be reproduced as a two dimensional image onto the surface, said image reproduced onto said surface by marking onto an unmarked portion of said surface only a single two dimensional image, an image upper surface being exposed, the three-dimensional model comprising a digital file; an imaging device movable over the surface and configured to reproduce the feature as said image on the surface at a first location based on a second location of the feature in the three-dimensional model, the second location of the feature defined by a first three dimensional coordinate system in the digital file, said second location of said feature with respect to said surface determined by correlating a position of the imaging device with respect to reference points comprising a digitally produced plane surface normal from a model surface of said three-dimensional model, said digitally produced plane surface not comprising said three-dimensional model, the position of the imaging device defined in a second three dimensional coordinate system different than the first three dimensional coordinate system; a tracker configured to track a three dimensional position of the imaging device, based on a coordinate system; a computer correlation program configured to correlate a position of the imaging device determined by the tracker with a three dimensional position of the feature in the three-dimensional model, to generate a correlated position of the imaging device, and to generate difference values between the position of the imaging device with the three dimensional position of the feature in the three-dimensional model; and, a controller configured to control operation of the imaging device based on the correlated position and to monitor the difference values with a set of preconditions.
