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

Embodiment Construction

[0114] It should be pointed out that the following detailed description is exemplary and intended to provide further explanation to the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0115] Such as figure 1 As shown, the crowd evacuation simulation method based on the heterogeneous emotional infection model includes the following processes:

[0116] Process 1: Initialization. The initialization here includes initialization of scene information, individual location information and emotion.

[0117] First, initialize the scene obstacles and draw the roadmap of the scene. The present invention uses the Roadmap to represent scene semantic information, and expresses the barrier-free area as a graph (Graph) structure through the Roadmap, which represents a topological graph that bypasses obstacles. The topological g...

Abstract

The invention discloses a crowd evacuation simulation method and system based on a heterogeneous emotional infection model. First, a method for calculating heterogeneous emotional infection based on the Durupinar model is designed. In this method, a group-based emotional infection calculation method is proposed. method, considering the influence of the two factors of distance and relationship between individuals on the grouping, and using the crowd grouping algorithm to group the crowd, and studying the influence of grouping on the calculation of emotional infection; on this basis, a feature-based calculation method of panic degree is proposed, according to Differences in characteristics of personality, gender, and age will specialize individuals, and use the above characteristics to calculate the degree of emotional panic. Secondly, the above-mentioned heterogeneous emotional infection model is coupled with crowd movement, and combined with the relative speed obstacle method, the crowd movement is driven by emotion. Finally, the effect of crowd evacuation is simulated by using photorealistic rendering. The invention can observe the phenomenon of emotional infection in crowd 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 ...
