1. A system and apparatus for making accurate dimensional or geometrical measurements of the features in a predominantly 2D scene from an image of the scene taken from even a non-orthogonal perspective comprising a. a digital scanner that creates digital image data; b. a reference object containing at least four co-planar reference fiducials physically placed proximate to the predominantly 2D surface containing the features to be measured. c. a data processing system that: i. contains information regarding the geometry of the reference template or reference object; ii. determines the locations of the coplanar reference fiducials within the digital image; iii. From the locations of the fiducials, determines the non-orthogonal distortion(s) of the objects features caused by the non-orthogonal viewpoint of the camera relative to the predominantly 2D surface; iv. determine corrections for the distortions; v. apply the corrections to compute accurate dimensions or geometry of features in the scene d. A user interface to allow user input and to output the accurate dimensions or geometry of the objects predominantly 2D surface. e.
