多样化虚拟人群生成方法研究

摘要

In crowd simulation,if all of the virtual characters look alike,it will appear to be clones and lack reality as in real world.The paper studies the diversified appearance of characters from aspect of models,textures,postures and so on.The paper realizes character model differentiation by using Hasler model library,achieves diversification of the appearance by texture templates,and obtains the various postures by skeleton embedding technology for the model.The results show that the proposed method can generate plausible virtual crowd with good diversity.%对于人群仿真中的人物角色来说,如果所有的虚拟人物外观都一样,那么就会给人简单复制品的感觉,真实感较差.研究人群角色外观的多样性问题,分别从角色模型多样化,纹理多样化和姿态动作多样化等方面进行讨论,采用Hasler模型库实现角色身高以及体型的差异化,通过纹理模板实现角色外观的多样化,并通过嵌入骨骼技术为模型赋予不同动作.实验结果表明本方法可生成效果较好、外观各异、动作多样的虚拟人群.
