PREPARATION OF LINE DRAWING EMBROIDERY DATA FOR COMPUTER EMBROIDARY MACHINE

摘要

PURPOSE:To make it easy to get data for embroidering an original picture in line drawing way by a method wherein the original picture is automatically analyzed in line segments, by programs stored in a microcomputer memory, and data regarding its transfer sequence, line thickness, line type and so on are automatically inputted in the RAM for an embroidery machine. CONSTITUTION:When an original picture 1 drawn in line drawing is automatically inputted, it is read by a image scanner 2 and they are stored in a X-Y RAM 5 by means of an interface 3 and an arithmetic unit of CPU 4. When it is manually inputted, it is read by digitizer 8 and they are stored in the X-Y RAM 5 by means of an interface 9. The original picture data in the X-Y RAM 5, then, are fetched again and they are computed by the arithmetic unit 4. They are inputted in a floppy disk 6 on a memory or in a RAM for a embroidery machine 7. The original picture is split in line segments by the arithmetic unit 4, which computes each line segment length, point intersected by other segments at both ends of a segment, line type, line thickness, starting point of segment sewing, the number of needlework on a segment and so on. A cloth frame is driven on the basis of these data and the line drawing embroidery is quickly made.
