The Application of Vectorization in Automatic Programming System of Cutting Plotter

The key technologies of image vectorization were presented, and they were applied in automatic NC programming system successfully. The pattern input is the scanning image of clothes、shoes or caps. After median filter, thresholding, boundary tracking, chain code tracking and polynomial fitting, the origin image is faired into lines and arcs. The application of this method extends the design instrument in automatic programming system of NC-cutter greatly.
