Method and system for simulating crowd movement in political assembly scene

Abstract

The invention discloses a method and system for simulating crowd movement in a political assembly scene. The method comprises the following steps: establishing a personalized model of an individual ina political gathering scene; presetting an initial viewpoint of an individual in the political gathering scene; according to the individual personality model of the individual in the political gathering scene, determining the outward nature and the same theory center of the individual; on the basis of the initial viewpoint, determining an emotion value of the individual at the current moment according to the outward property and the similar center of the individual in the political gathering scene; establishing a social force model based on the emotion value and the emotion infection direction of the individual at the current moment; and simulating the movement of the individual in the political gathering scene according to the social force model. According to the method, crowd emotion infection under two opposite viewpoints is fully reflected, and crowd emotions are applied to individual behavior decision making, and crowds in a political assembly are simulated through combination ofindividual emotions and social force models, and the simulation result is good.

Description

technical field [0001] The present invention relates to the technical field of crowd movement simulation, in particular to a method and system for simulating crowd movement in a political rally scene. Background technique [0002] In the field of computer graphics, some typical research scenarios of group behavior simulation mainly include mob riot scenes, station squares during peak periods, and natural disasters such as fires and earthquakes. The crowds in these scenes have some similarities with the crowds in political rallies in terms of emotional diffusion and behavior modeling, but they fail to fully cover all kinds of crowd behaviors in complex political rallies. For example, research on mob behavior is mainly to classify people in riot scenes and analyze the behavior of different types of thugs. This type of technical solution mainly studies the spread and action process of a certain emotion of mobs in the crowd, and does not involve the emotional infection among in...
