人体模型自适应变形算法的研究与实现

摘要

The distortion that human model surface penetrate clothing will happen in the virtual fitting personality adjustment process when garment's size fit human model. To address it, a human model adaptive deformation algorithm is proposed, through adding mass-spring system in the needed adaptive deformation area, and adding a new class of spring-supporting spring in the system, making the model surface closer to the real situation of the human body. And the algorithm is researched and analyzed, which a improved algorithm is carried out for improving the deficiencies. Experimental result shows that this algorithm is efficient and its response time is short, after using it, human model can be adaptive deformed by the shape of clothing and has the circumference invariance, and a more satisfactory fitting results is achieved.%针对虚拟试衣个性化调节过程中服装尺寸符合人体模型时出现的人体模型表面穿透服装的失真现象,提出一种人体模型自适应变形算法,通过在需要自适应变形的区域加入质点弹簧系统,并在该系统中加入了一类新的弹簧——支撑弹簧,使得模型表面更接近于真实人体的情况,并对实现算法进行了研究和分析,针对存在的不足进行了改进.实验结果表明,该算法运算效率较高、响应时间短,使用后人体模型能够针对服装的形状进行自适应变形,并具有围度不变性,实现了较为理想的试衣效果.
