Application of image processing methods in CAD/CAM systems for knitting industry automation

This paper treats the problems relate with image processing in CAD/CAM systems' software in knitting industry automation. The graphics images and theirs processing are the base part from the CAD/CAM systems' software. The other most important part of it is the design procedures for an automatic creation of execution units control programs. In the knitting industry, these programs control the knitting machines for creation of determined knitting structures and products, which is closely related with object images. In this paper, the image processing methods for knitting industry automation are suggested. The using methods suggested in this paper are: transformation of gray level images to binary images; path tracing for recognition of digital straight line. The trace algorithm is extended by operations: translation of the current dot; next dot searching in next levels. This method is reliable in a CAD/CAM system for cotton knitting industry automation. The algorithm is used is the CAD/CAM system's software.
