摘　　要：在虚拟角色仿真过程中,虚拟人物外观多样性很大程度上取决于角色模型本身的差异性。而角色模型的差异性主要体现在两方面:模型的高矮胖瘦以及模型穿戴的头佩附件。为体型各异的角色模型自动穿戴合适的附件可大大增强仿真的真实感。基于此问题,提出一种头佩附件自动组合算法,首先为角色模型自动嵌入骨骼,其次为附件模型添加简单骨骼并选取骨骼的锚点,再通过附件自动组合算法快速生成组合角色模型,最后通过嵌入的骨骼驱动该组合模型运动。实验证明该方法简单快捷,能够为多样化的角色模型自动穿戴头佩附件,提高角色模型的多样化程度。The diversity of virtual humanfor simulation is mainly exhibited by the character. The differences between models consist of two parts： the somatotype and the head accessories. Automatic matching head accessories for virtual human will observably increase the realistic of the simulation. A new method for automatic matching is presented. Firstly, we assign simple skeleton to the accessories and choose anchor points after automatic rigging skeleton for virtual models, then execute the matching method to achieve matched model. Finally, we assign various postures to the model by embedskeleton. The result shows our method can match the head attachments to diverse virtual human automatically, and pretty improve the diversification of virtual models.
