Abstract


With the continuous development of computer software and hardware technology, more and more industries are to alter the mode of production, combined with computer applications makes the original tedious work becomes simple and effective. Computer applications in the apparel industry are constantly attention and study, anthropometric measurements, cutting, stitching, model fitting requires the participation of designers and models in the original production of clothing, so that the efficiency is very low and not suitable for large-scale production. The concept of the combination of information technology and personalized tailor MTM (Made to Measure) is the 21st century the rise of a new garment production methods - electronic the tailored eMTM the (ElectronicMade to Measure), it is the use of modern three-dimensional body scanning technology, computer graphics technology and network technology, garment production in the human body measurement, body type analysis, all aspects of the style choices, fashion design, clothing display clothing order clothing production organically combined together, to achieve fast and efficient digitization clothing production. Personalized, the dynamic virtual human model helps to demonstrate the effect of real human wearing apparel the study dynamic virtual human model building is an important part of the eMTM system. Papers oriented eMTM personalized dynamic virtual human model are discussed in detail in the analysis of the virtual human body surface data generated by the three-dimensional body scanning equipment, redundant data removal and re-organization of virtual human body the surface structure of the data, and with reference to the H-Anim standard (Humanoid Animation Working Group definition of a display in VRML virtual human standards) generates a virtual human body model having a hierarchical structure, combined with the characteristics of the H-Anim virtual mannequin, using positive The kinematics achieve a dynamic display of the virtual human model. In order to better show the dynamic effect of the virtual human model, to solve virtual human model surface discontinuity caused \The real-time calculation of the surface in the course of the campaign, an effective solution to the virtual human model in motion \Based on the above research, the paper presents a method to reconstruct human data generated by the three-dimensional body scanning equipment, according to the data of the surface of the human body scanning system in line with the basic characteristics of the real body size, so this method makes the building of virtual The human body model with personalization features. Thesis refers to the H-Anim standard in order to make the virtual human model built to be able to dynamically display combined Java3D 3D scene description language features will save virtual human model according to the hierarchical tree structure. The paper also studied the way the surface of the human body after data sparse tiered storage, this storage method combined with the rotation of the three-dimensional spatial coordinates calculation processing discontinuous phenomenon of the surface during movement of the virtual human body model can be effectively solved.
