Embodiment Construction

[0025] The present invention will be further described below in conjunction with the drawings and embodiments.

[0026] Such as figure 1 Shown is a simplified flow chart of the present invention, where

[0027] Scene initialization: The scene is a roadmap, and the scene information is divided into obstacles and barrier-free areas. The barrier-free areas are expressed as a graph structure, which represents a topology map that bypasses obstacles. The topological graph is composed of vertices and edges G=(V,E). Where V represents the set of vertices, E represents the set of edges, each edge e(v 1 ,v 2 )∈E, where vertex v 1 And vertex v 2 Are the two endpoints of side e. The edges of the Roadmap connect the vertices, connecting any two vertices with a distance of r, and at the same time, ensure that the connection between the two vertices does not pass through any obstacles.

[0028] Initialization of individual position: Considering the scene information and obstacle information comp...

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 individualized crowd animation for emotional infection. Background technique [0002] There are frequent emergencies in large public places, and how to evacuate people quickly and safely is a hot issue in the field of safety research. The current traditional evacuation drill methods cannot truly simulate the evacuation of people in emergencies. During the evacuation of people in emergencies, there will be a phenomenon of mutual emotional infection among the crowd during the evacuation process. For people of different personalities, emotional infection will be affected to varying degrees. Simulating crowd movement affected by emotional factors not only needs to consider the influence of emotional infection on sports, but also the influence of individual personality on emotional infection. Therefore, simulating the influence of real personality on emotional infection is of great significance, and it is also v...
