The Design And Implementation Of The Crowd Simulation System Based On The New Emotion Contagion Model

In recent years,with the rapid development of computer operation speed and the computer graphics,the crowd simulation technology has gradually become a research focus.As a branch of simulation technology,crowd simulation has high practical application value.It plays a great role in some major accident scene simulation technology,researchers can simulate the field situation in advance using simulation technology and provide data support for the design of buildings and disaster emergency plan.With a view to improving the verisimilitude of original simulation technology,researchers try to combine emotional contagion and personality;at the same time in order to better express the relation between personality and emotional contagion,the process of emotional contagion and influence of emotional contagion,researchers do quantitative description of emotion model.But the existing model still have some problems leading to the lack of verisimilitude,so this paper establishes a completely new emotional contagion model and implements it with basic theory of emotional contagion as a reliable theoretical basis and combining the personality description model,in order to improve the fidelity of simulation system.At the same time,in order to improve the result while increasing the performance,this paper improves the layered technology of potential field on the basis of system implementation.This paper clears the function distribution,especially clear and define the function of local potential field and select the appropriate algorithm,finally achieve a better balance of performance and result.Finally,a complete set of simulation system based on emotional contagion model has been completed including the emotional contagion model,the path planning module,existing collision avoidance module and the visual module.For purpose of verifying the validity of the model,this paper selects a scene of emergency evacuation to execute crowd simulation system,get the simulation data and the dynamic effect diagram through the visualization module and compare them with the prior data.Through the data comparison,it can be proved that the new model of emotional contagion is more accurate to describe the emotional contagion,which is more close to reality.
