摘　　要：当前基于情绪的人群动画方法没有考虑个性对情绪感染的影响。现实中的人群情绪(如恐慌、焦虑等)往往存在个体差异性,从而会对人群的情绪感染产生重要的影响。为生成更为逼真的人群动画,提出一种基于个性化情绪感染的人群动画生成方法。该方法包含3部分:首先,建立了一个基于情绪感知因子的个性化Durupinar情绪感染模型(Personalized Durupinar,P-Durupinar),该模型能够有效体现人群情绪的个体差异性;其次,将P-Durupinar情绪感染与人群运动耦合,结合相对速度障碍法,利用个性化情绪驱动人群运动;最后,使用真实感渲染方法生成人群动画。实验结果表明,基于个性化情绪感染的人群动画生成方法能够更逼真地仿真人群的社会行为。At present,most of crowd animation methods only simulate the emotion of behavior rather than consider the impact of human personality on the emotion.In the real world,one＇s emotion（e.g.,panic,anxiety）often differs from others which is called personality difference.In order to generate more realistic crowd animation,we presented a crowd animation method based on personalized emotional contagion model.The method is divided into three parts.Firstly,we provided the emotion perception factor and introduced the P-Durupinar model which shows the crowd＇s diversity effectively.Secondly,the P-Durupinar model was coupled with the crowd motion.Combined with the reciprocal velocity obstacle,we could activate the crowd＇s motion.Finally,the photo-realistic rendering method was employed to obtain the crowd animation.Experimental results show that our personalized emotional contagion-based crowd animation method can simulate the crowd social behavior more realistically.
