摘　　要：针对服装设计作品从实物到数字模型生成需要通过数据重构达到倍增设计量的问题,提出服装逆向数字化造型设计方法。首先通过三维扫描得到设计作品点云数据后,经过去噪、修补和预处理,简化并拓扑为四边形网格;再对奇点形成的异形网格进行曲面重构设计,包括奇点的位置调整、数量增减和形态变化,为服装逆向造型延展设计提供参照依据;最后进行纹理、颜色和材质的映射还原,实现逆向思维的服装造型数字化模拟。研究表明:逆向造型的数字化设计方法提升了数据复原和保存的效率与精确度;逆向造型延展设计实现了快速增加二次造型设计量,且完善后的延展设计作品模拟可反向拓扑服装的版型图纸,也为服装版型设计和同类型服装结构优化奠定基础。Objective Aiming to obtain doubled amount of design through data reconstruction during generating the digital model from the physical object of the design work,a digital design method of clothing reverse modeling is built up.It mainly addresses two problems:one is to restore and save the data of irreproducible clothing,the other is to carry out reverse modeling and extension design of excellent clothing works.Methods The point cloud data obtained through 3-D scanning were simplify,and the topology into a quadrilateral grid was optimized.Then,surface reconstruction design was carried out on the special-shaped grids caused by singular points,with position adjusting,quantity increasing and decreasing,and shape changing.As the last step,the digital simulation design of clothing modeling was set up following reverse engineering through mapping and restoration.Results The clothing design ideas and methods were submitted based on the reverse modeling process(Fig.1),which could restore quickly the virtual experimental objects and provide designers with new design methods and skills for secondary expansion modeling.The rationality of the pattern structure was verified by the three-dimensional effect of the clothing and the actual object with distinctive features.First,it collects,restores and stores data of irreproducible clothing by clothing models acquiring model topological surface reduction,modeling structure splitting,and texture mapping(Fig.2).Second,it calibrates the position of the singularity to provide a reference method to quickly carry out reverse modeling and extension design on excellent clothing works(Fig.3).Third,it carries out extension modeling by adjusting the position of the singularity,increasing or decreasing the number,changing the shape of the surface reconstruction design,and making a real entity for objective verification(Fig.4).The shape and structure of improved extension design work could be transformed into planes,and the pattern drawing of the reverse topology clothing provides a basis for p
