基于Python的女式衬衫版样自动化生成技术

Automatic Generation Technology of Women's Ahirt Template Based on Python

为解决自动化制版技术与工业化生产设备的兼容性等问题,结合Python语言和AutoCAD二次开发功能,提出了一种女式衬衫参数化版样自动生成技术。通过分析版样曲线拟合原理,设计3种“离散曲线”算法。根据女式衬衫制版原理计算各控制点与领围、胸围、衣长、袖长和袖头宽5个关键参数的线性关系,搭建女式衬衫参数化算法模型框架,并采用MATLAB拟合工具箱Curve Fitting Tool进行曲线真值拟合误差比对。结果表明:女式衬衫参数化版样自动生成技术可以实现个性化纸样的快速生成;自动生成版样可作为车间数控裁剪设备的走刀路径,用于实现全自动化生产;自动生成的曲线真值拟合误差各参数良好,手工制版与自动生成的曲线拟合相似度接近。该技术可应用到其他服装品类,提高服装个性化定制的快速反应能力。

In order to solve the problem of compatibility between automatic platemaking technology and industrial production equipment,combining Python language and AutoCAD secondary development function,an automatic generation technology of parametric sample of blouse was proposed.By analyzing the model curve fitting principle,three"discrete curve"algorithms were designed.According to the platemaking principle of women's blouse,the linear relationship between each control point and five key parameters including collar circumference,chest circumference,garment length,sleeve length and sleeve width were calculated,and the parametric algorithm model framework of women's blouse was built.MATLAB Curve Fitting Tool was used to compare the fitting errors of curve true value.The results showed that the automatic generation technology of parametric pattern could realize the rapid generation of personalized pattern.The sample could be used as the cutting path of CNC cutting equipment in the workshop to realize fully automatic production.Automatically generated curve true value fitting error parameters were good.Manual plate making and automatically generated curve fitting was similar.The technology can be applied to other clothing categories to improve the rapid response ability of personalized clothing customization.
