摘要
基于面向对象技术,在深入研究DST、DSB和DSZ等主流缝纫花样格式的基础上,设计出花样拟合信息和缝纫控制信息相分离的SDT/BAS二元花样格式。介绍了SDT/BAS二元花样格式的特点。分析了原花样格式二次定制时失真原因,在此基础上阐述了SDT/BAS花样格式二次定制的保真性原理。目前,此种新型花样格式已应用于自主研发的电脑花样机系统,能高效且保真地实现花样二次定制,并且高效配合缝纫运动。
Based on object oriented technology,by analysis of other mainstream sewing pattern formats,such as DST、DSB and DSZ,this paper brings up a new type of dual structure sewing pattern format-SDT/BAS-which separates the information of curve fitting and sewing control movement.The characteristics of SDT/BAS pattern format have been described.By analysis of distortion emerged in secondary customization of those traditional pattern formats,the high-fidelity algorithm principle of pattern transformation has been introduced.At present,using the SDT/BAS pattern format in our new self-developed computer sewing machine system,the machine system＇s efficiency of secondary customizing and sewing movement can be evidently increased.
