Population evacuation simulation method and system based on heterogeneous emotional contagion model

Abstract

The invention discloses a population evacuation simulation method and system based on a heterogeneous emotional contagion model. Firstly, a heterogeneous emotional contagion calculation method based on a Dupirinar model is designed. In the method, an emotional contagion calculation method based on grouping is proposed, influences of two factors of individual distance and relationship on the grouping are considered, a population grouping algorithm is used for grouping the population, and the influence of the grouping on the emotional contagion calculation is studied. On this basis, a method forcalculating the degree of panic based on characteristics is proposed, individuals are specilized according to characteristic differences in personality, gender and age, and the degree of panic is calculated by using the above characteristics. Secondly, the above heterogeneous emotional contagion model is coupled with population movement, a relative speed obstacle method is combined, and emotionsare used to drive the population movement. Finally, a realistic rendering method is used for simulating a population evacuation effect. The population evacuation simulation method and system based onthe heterogeneous emotional contagion model can observe emotional contagion phenomena in the population movement more realistically and intuitively.

Description

technical field [0001] The invention relates to a crowd evacuation simulation method, in particular to a crowd evacuation simulation method and system based on a heterogeneous emotional infection model. Background technique [0002] The use of crowd motion simulation to study crowd movement characteristics and laws in emergencies can help designers to conduct comprehensive analysis and evaluation of the evacuation channels of buildings or public places, assist in the establishment of emergency evacuation plans, and reasonable The building layout is designed to reduce the occurrence of adverse events such as crowding and stampede in group events, and is conducive to crowd evacuation in emergency situations. In the process of crowd evacuation, individuals tend to gather into small groups, and there are individual differences within groups, but most of the existing emotional infection models do not consider the influence of group and individual differences on emotions, and the ...

AI Technical Summary

Problems solved by technology

In the process of crowd evacuation, individuals tend to gather into small groups, and there are individual differences within groups, but most of the existing emotional infection models do not consider the influence of group and individual differences on emotions, and the infection among individuals is isomorphic , that is, the infection speed among individuals is the same, which cannot realistically simulate the crowd movement process
