摘　　要：为表征同一号型下的人体体型形态差异,选取与原型样板密切关联的肩部、胸部及腰部水平特征截面进行研究。通过[TC]^(2)获取145名18~25岁青年女性的三维点云数据,选取占比最高的160/84 A体型样本,采用K-means聚类进行体型细分,提取肩部、上胸围、胸围、下胸围、腰围5层水平特征截面,运用极径表征形态差异。研究结果表明:同一国标号型身高胸围数据虽然相似,但存在形态差异;160/84 A体型可分为圆厚体、宽扁体、中等体,分别占比7.69%、53.85%及38.64%。3类体型中宽扁体肩宽>中等体肩宽>圆厚体肩宽,肩点处最大极差为3.82 cm。圆厚体的上胸围厚、胸围厚和下胸围厚最厚,其次是中等体胸围厚,宽扁体的胸围厚最薄,在前中处最大极差分别为3.22、3.62和2.97 cm。宽扁体较圆厚体、中等体肩点位置向前中方向偏移10°,宽扁体、中等体胸点位置较圆厚体向侧缝方向偏移10°~20°。Objective Human morphology characterization and quantification play an important role in garment fit,pattern generation and body type classification.The characterization and differential analysis of human morphology under the same number of sizes deserves to be explored in depth.To characterize the morphological differences in body surface shapes under the same size category,this study is focused on the shoulder,chest,and waist horizontal-sections related to the prototype pattern.Method The three-dimensional point cloud data of 145 young women aged 18-25 years were obtained through[TC]^(2).Samples with the highest proportion of size 160/84 A were selected.K-means clustering was used to quantify the morphological characterization after subdividing the body types that accounted for the largest proportion of the body type,extracting the horizontal circumference cross-section curves of the shoulder,upper bust,bust,under bust,and waist of each classified intermediate body.Due to minor movements or variations in standing posture during 3-D scanning,coordinate system discrepancies may be appeared between the characteristic cross-sections and the system coordinate system.To address this problem,the smallest external rectangle method was applied to align the x and y axes of the characteristic cross-sections in the system coordinate system.Then,each horizontal cross-section was aligned with the mass center as the origin.Subsequently,the cross-section polar diameters based on each body shape morphology were used to plot the centroid-curve for morphological quantification and analysis.Results The body type of 160/84 A was divided into round-thick body,wide-flat body and medium body,accounting for 7.69%,53.85%and 38.64%,respectively.The average chest circumference and waist circumference of three types of 160/84A sub-body types were(83.70±0.56)cm and(66.84±5.57)cm,respectively.The shoulder width of the three sub-body types was found to follow the order of wide-flat body>medium body>round-thick body,with a maximum range of 3
