In crowd simulation, 3D (three-dimensional) character modeling is an important topic since the appropriate character models are helpful to improve the efficiency and realism of crowd simulation. The reconstructed 3D character model based on Kinect has a strong sense of reality and low cost. However, these models are all complex and cannot be applied to large-scale crowd simulation directly. In this paper, we propose a novel personalized human body modeling method for mass crowd simulation based on Kinect. The human modeling process is divided into head modeling and torso modeling, and then they are fused into each other to build a personalized human body model. This method can be divided into two parts: In the first part, a simplified method is presented based on edge curvature and area of error. In addition, to preserve the detail characteristics of model, the way of interactive operation is introduced. In the second part, the automatic fusion for the simplified head model and body model is made by using the improved FCF (fusion control function) fusion method. Finally, a hierarchical database for the personalized human body models is built. The experiment results show that the method proposed in this paper has high efficiency and good robustness in practical applications.

“…We randomly assign emotional states to each individual and propose S vir (i), P vir (i), S phy (i) and P phy (i) based on personalized emotional states. According to the literature [52], the S vir (i), P vir (i), S phy (i) and P phy (i) of individuals can be divided into four levels corresponding to four different emotional states. Without loss of generality, we suppose that these variables are subject to a uniform distribution U (•), as shown in Table 2.…”

“…In the [51], the individual's susceptibility positively related to the sensitivity of the individuals. In addition, individuals with different personalities have heterogeneous infection and cure rate which will affect the emotional contagion directly [52], [53]. Considering the individual personality differences, we regard that the infection rate of the individual is affected by the own strength of emotional contagion and the infection rate of the infected individuals.…”

Asymmetric Intimacy Based Positive Emotions Contagion Peer Public Safety Evacuation Behavior

et al. 2020

Behavioral simulation plays an important role in many scenarios, such as emergency evacuation and public safety. The importance of public security in modern life can be seen in the epidemic outbreak in 2020. In particular, the epidemic can affect people's psychology and emotions and change people's behavior. Therefore, how to effectively improve people's positive emotions in a panic has become an urgent problem. In social relations, most behaviors are produced by peer interaction. To simulate the interactions among peers more realistically, this paper studies the diversity and efficiency of evacuation behaviors from the trust of peers, the strength of social relations and empathy. First, a general framework of peer relationships is constructed based on asymmetric intimacy, including the relationship between intimacy relationship modeling. Then, the problem of the dynamic formation of peer groups is studied by employing the calculation method of asymmetric intimacy. The effect of positive emotion transmission mechanism on peer interaction behaviors is explored through asymmetric intimacy. Finally, the companion behaviors of the peers in several scenarios are simulated. The proposed method is compared with different emotion contagion models and the behavioral simulation models. Experimental results show that the positive emotions contagion of the peer behavior simulation method can concrete the macro group behavior and effectively simulate the peer group in an evacuation. The simulation effects are diverse and efficient.
