Abstract
In a method for compensating for pattern distortion of sheet-type work material spread onto a support surface a processing apparatus is provided and carries said support surface. The work material is spread onto the support surface and images of selected areal portions of the work material are captured. A controller analyzes these images and projects them onto a display whereupon the images are mapped to define any distortion in the work material. The controller then undistorts the images of these areal portions and projects them back onto the display so that an operator can position undistorted digital representations of pattern pieces onto the undistorted images of the work material. The controller then distorts the geometry of the pattern pieces positioned on the work material by the operator to conform to the distortion in the spread material.
