摘　　要：在虚拟试衣系统中,所用的衣物模型都是预先制作好的三维网格模型.为了使虚拟衣服针对不同用户进行"量体裁衣",就必须对其进行网格模型变形.提出了一种基于人体轮廓图驱动的三维模型变形方法来生成与用户体型相符的衣物模型.该方法包括对网格模型的编码、选择和移动锚点,求解能量优化问题,最终得到变形后的网格,并通过网格简化操作加速网格变形,使得模型变形算法效率大大提升,论证了将模型变形应用于虚拟试衣系统的可能性.In virtual dressing system,all the clothes are three-dimensional(3D)mesh model which was made previously.To make virtual clothes match different users more accurately,we need to deform these mesh models.In this paper,an image-drive model deformation method was proposed to get a model which was adjusted to match user′s body shape.This method includes coding,selection and movement of anchors,solving energy optimization,and finally deformed mesh was got.The algorithm is made more efficient by simplifying mesh.The possibility of model deformation using in virtual dressing system was proved.
