Abstract:
A method for compensating for pattern distortion on sheet-type work material spread onto a support surface, said method comprising the steps of:providing at least one layer of sheet-type work material defining a pattern thereon; providing a work material processing apparatus having a frame and a support surface carried by said frame; spreading said work material onto said support surface; providing means for capturing images of areal portions of said work material when spread onto said support surface; providing a controller programmed to analyze distortion in said pattern defined by said work material, said controller being in communication with said means for capturing an image of said work material; providing a display in communication with said controller; capturing images of said areal portions of said work material spread on said support surface and transmitting said images to said controller; projecting said images onto said display based on signals transmitted from said controller; mapping the distortion of said pattern defined by said areal portions of said spread work material; causing said controller to undistort said images of said areal portions and projecting undistorted images of said areal portions onto said display; positioning undistorted digital representations of pattern pieces onto said undistorted images of said work material; and causing said controller to distort geometry defined by said pattern pieces to correspond to the pattern distortion of said areal portions of said work material so that when said pattern pieces are cut from said spread work material the pattern therein will be undistorted.
