Cloth pattern distortion compensation method in cloth cutting apparatus, involves distorting pattern geometry after positioning undistorted digital pattern representation on undistorted images of work material

摘要

The captured images of areal portions of a work material (26) spread on a support (14), are projected on a display (30) and mapped to determine distortion in work material. The images are undistorted by a controller (18), over which the undistorted digital representation of patterns are positioned. The geometry of the patterns is distorted corresponding to the actual pattern distortion.
