Abstract
An automatic quilting machine for use in stitching individual selected patterns into a large fabric such as a bedspread or quilt. The bedspread or quilt is stretched on a large metal frame which is mounted on a table which can be moved in the X-direction, the Y-direction, or any X-Y combination direction through a process controller. The precise location of a sewing machine needle and fabric is illuminated and a color video camera which is mounted on a cross beam holding a sewing machine head is also focused on this location. The color video camera is connected through a preprocessor and a frame grabber to a process controller. A pattern creation means is also connected to the preprocessor and through the frame grabber to the process controller. The process controller includes a Machine Vision - R program which takes the pattern created by the pattern creation means and converts it into a pixel. The pixel is then mapped on a grid to determine the locations where the pattern is to duplicated. The process controller can then cause the pattern to be subsequently repeated at any multiplicity of desired locations.
