基于服装结构的衣片自动推裆算法

尽管服装的款式不一,但其基本的服装结构总是一定的,且其结构框架线也是一定的。本文基于服装结构,应用结构参数增量法,直接计算出相应的结构框架线的增量,进而计算出衣片上各特征关键点的推裆增量,实现了服装衣片的自动推裆计算。给衣片特征关键点附加的入射角与出射角属性,保证了衣片弧线拟合的平滑性。本方法易于实现,有简单适用性较广之特点。     

Automatic Assessment of Fabric Smoothness Grade Using Double CCD Grating Projection

Automatically assessing fabric smoothness grade is very important in the evaluation of fabric appearance. A system for objectively evaluating the fabric smoothness grade based on a grating projection unit and double colored CCD (short form of charge coupled device) was constructed in this paper. Two images captured by different CCD compensated each other which reduced the influence of noises. The application of the four-step phase-shifting method enabled the calculation of the exact phase in a point easy and quick. A large amount of 3D points with three coordinates X, Y and Z were obtained precisely making the definition and calculation of fabric smoothness characters easy. Then four parameters which intuitively denoted the fabric smoothness degree were obtained. Finally, a proper neural network was built, which successfully performed the fabric smoothness classification. The experimental results show that the system is applicable for all the fabric whatever pattern or color. The experimental grades provided by this grating projection system are also highly consistent with the subjective results.     

Subjective and Objective Measurements to select Fabric for Child Patients'''' Garment

This paper studies on fabrics suitable for child patients'garment in the hospital environment in Hong Kong,China.Subjective measurement was carried out by questionnaire survey to consult medical staff on hospital requirement about fabric criteria for child patients' garment. On the other hand, objective measurement was conducted by performing laboratory tests on fabrics,which were sourced from commercial fabric market. Both measurements are evaluated according to the results on those fabric criteria in order to determine the most suitable kind of fabric for the end purpose. As a result of the comparison, it was found that T/C 1 scores the highest index. Therefore, it will be suggested for manufacturing child patients' garment to evaluate the fabric suitability to meet the wearers' requirement through hospital trial.

Effect of Fabric Elongation on the Making Up of Pressure Garments

Pressure garments are widely used in Hong Kong andmany other countries for burn rehabilitation.Thesegarments are mainly made of elastic Lycra fabrics andtailor-made to individual patient's measurement toprovide an appropriate amount of skin-garment in-terface pressure for medical treatment.However,thefabric tension would be reduced due to fabric elonga-tion under prolonged period of stress,and thus theskin-garment interface pressure cannot be main-tained after repeated use of the garment.This paperaims to study the behaviour of fabric elongation of thefabrics commonly used for making pressure garmentsin U.K.and/or Hong Kong.Attempts to correct theexisting practice of drafting the pressure garments forproviding a more effective clinical treatment.

基于关联规则及组合模型的面料需求预测

由于服装的面料组成具有复杂性,企业在不同时间对不同规格型号面料需求量不一致,传统的人工预测及单维度智能预测模型难以解决问题。针对服装企业面料需求非确定性、预测难的痛点,提出基于关联规则及组合模型的面料需求预测方法。文章首先构建Apriori面料型号关联模型,挖掘多批多类面料间的型号关联规则;然后构建Prophet时间序列模型与长短期记忆神经网络(long short-term memory,LSTM)的组合预测模型Prophet-LSTM,结合其在解决面料需求预测问题上的优势;最后将挖掘出的高关联面料型号历史需求数据作为输入,采用量子粒子群算法(quantum particle swarm optimization,QPSO)优化组合模型权值系数,进行关联面料需求量预测。使用RMES(root mean squared error,RMSE)及MAE(mean absolute error,MAE)作为评价指标设计对比实验,实验结果表明：采用量子粒子群优化的QPSOProphet-LSTM面料需求预测模型RMES较Prophet降低5.464,较LSTM降低1.184;MAE较Prophet降低4.261,较LSTM降低0.819,需求预测精度更高,支持服装企业面料柔性生产。
