Abstract

The invention discloses an emergency crowd evacuation simulation method and system based on a group effect. The emergency crowd evacuation simulation method comprises the steps that (1) building a scene model and an individual model in a Unity 3D scene; Step (2), creating an interaction relationship between scenes and individuals, creating an interaction relationship between individuals, and generating an emergency scene; And step (3), realizing emergency crowd evacuation simulation based on a group effect in an emergency scene. According to the crowd evacuation simulation method, the advantages of unity3D software are utilized, a scene is more conveniently set up, modeling is conducted through multi-body dynamics crowd simulation and cohesion models based on the position, a model and a social model, and a built role animation controller is utilized, so that the crowd evacuation simulation process is smoother, more stable and more efficient.

Description

technical field [0001] The invention belongs to the technical field of virtual reality simulation, and in particular relates to a group effect-based simulation method and system for evacuating emergency crowds. Background technique [0002] Crowd simulation has been widely used to simulate emergency scenarios, understand human behavior in simulation, handle diversity among groups, evacuate from public buildings faster, and save more lives. The emergency is a kind of unforeseen, when the emergency occurs, people tend to respond slowly to the evacuation alarm, and take the familiar route instead of fleeing from the nearest exit. These dangerous behaviors are all due to unfamiliarity with the environment, failure to immediately recognize the dangerous situation, and following the unsafe behavior of others. And in the process of crowd evacuation, arch phenomenon, influence of obstacles, interference, herd behavior, fluid behavior, etc. will also appear. From the perspective of...
