Fitting an elegant 3D garment model onto a target 3D human model is crucial for garment design industry and virtual try-on systems. The alignment of the garment onto virtual try-on systems is currently the main limitation to propose an efficient virtual try-on system without use of reference body. We propose a new system of fitting a given garment onto a target human body with various shapes and postures. The key novelty of our work is the use of Hermite radial basis functions to approximate and to deform the garment mesh to fit the posture of the target human body. After the garment deformation, we adjust the global orientation of the garment based on the key joints of the garment skeleton and human skeleton. Thus, the garment model is positioned automatically around human body. We resolve the potential interpenetration between the human model and the garment using collision handling algorithm. We perform wrinkle synthesis of the garment to generate a natural and realistic shape. Our fitting method is effective for garment transfer, and the results obtained demonstrate that it produces believable fitting data and it is very satisfactory in terms of performance.

将优雅的 3D 服装模型安装到目标 3D 人体模型上对于服装设计行业和虚拟试穿系统至关重要。服装在虚拟试穿系统上的对齐是目前提出不使用参考体的高效虚拟试穿系统的主要限制。我们提出了一种新系统，可以将给定的服装以各种形状和姿势贴合到目标人体上。我们工作的关键新颖之处在于使用 Hermite 径向基函数来近似和变形服装网格以适应目标人体的姿势。服装变形后，我们根据服装骨架和人体骨骼的关键关节调整服装的全局方向。因此，服装模型自动围绕人体定位。我们使用碰撞处理算法解决了人体模型和服装之间潜在的相互渗透。我们对服装进行皱纹合成，以生成自然逼真的形状。我们的试衣方法对于服装转移是有效的，获得的结果表明它产生了可信的试衣数据，并且在性能方面非常令人满意。
