Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 Shown is the flow chart of the present invention simplification, wherein

[0026] Scene initialization: the scene is a roadmap graph, and the scene information is divided into obstacles and barrier-free areas. The barrier-free area is represented as a graph (Graph) structure, which represents a topology map that bypasses obstacles. The topological graph consists of vertices and edges G=(V,E). Where V represents the set of vertices, E represents the set of edges, and each edge e(v 1 ,v 2 )∈E, where vertex v 1 and vertex v 2 are the two endpoints of edge e. The edges of the Roadmap are connected to the vertices, and any two vertices with a distance of r are connected, and at the same time, it is necessary to ensure that the connection between the two vertices does not pass through any obstacles.

Abstract

The invention relates to a personalized emotional contagion population animation generation method. The personalized emotional contagion population animation generation method includes the specific steps: setting scene information which includes the barrier position and the barrier free area, and setting individuals in the barrier free area randomly, wherein the individuals include the individuals without emotional contagion and the individuals with emotional contagion; setting the target position of each individual; initializing the velocity and direction of movement of the individuals without emotional contagion and the individuals with emotional contagion, wherein the velocity of movement satisfies limitation of a maximum velocity vmax and a maximum acceleration amax, and vmax<=7m / s, and amax<=5m / s2; initializing the emotion value ea and the panic value qa of the individuals without emotional contagion, and the emotion value eb and the panic value qb of the individuals with emotional contagion, wherein ea=0, eb belongs to (0,1], qa=0, and qa<qb; and setting a fixed time interval as a time step, updating the emotion value and the velocity of movement of the individuals within one time step, and according to the individual emotion value and the velocity of movement of each time step, generating population animation.

Description

technical field [0001] The invention relates to a method for generating crowd animation with personalized emotional infection. Background technique [0002] With frequent emergencies in large public places, how to quickly and safely evacuate crowds is a hot issue in the field of security research. At present, traditional evacuation drill methods cannot truly simulate crowd evacuation under emergencies. In crowd evacuation under emergencies, there will be a phenomenon of crowd emotional mutual infection during the evacuation process, and for people with different personalities, emotional infection will be affected to varying degrees. To simulate crowd movement affected by emotional factors, it is necessary to consider not only the influence of emotional contagion on sports, but also the influence of individual personality on emotional contagion. Therefore, simulating the impact of real personalities on emotional contagion is both important and challenging. In the current r...
