基于通用型人体模板数据库的三维服装人台生成

摘要

In light of the inadequate support of existing clothing body modelling method on nonstandard human bodies , in this paper we propose a modelling method for universal-type 3D clothing mannequin modelling .On the basis of analysing existing scanned 3D data of standard and nonstandard human bodies , we establish a universal-type human body template database and the correspondent automatic selection algorithm through defining the feature parameters suitable for universal-type human bodies so as to solve the problem of modelling distortion in nonstandard human bodies .Template matching algorithm is used to extract similar parts , after the curve fitting and interpolation processing , the human body model is generated .Experiment results shows that the use of this method effectively resolves the distortion problem in nonstandard human body modelling , the human bodies established with both standard and nonstandard body sizes gain noticeable improvement on speed and accuracy , this lays a foundation for the popularisation and application of eMTM .%针对现有服装人体建模方法中对非标准人体的支持不力，提出通用型三维服装人台的建模方法。在分析已有的标准和非标准人体的三维扫描数据基础上，通过定义适用于通用型人体特征参数，建立通用型人体模板数据库和相应的自动选取算法以解决非标准人体建模失真问题。由模板匹配算法从中提取相似部件进行曲线拟合插值处理后生成人体模型。实验结果表明，利用该方法有效地解决了非标准体型人体建模失真问题，并且所建立的标准和非标准体型人体在速度和精度上都得到明显的提高，为eMTM（ electronic Made To Measure ）的普及应用奠定基础。
