Embodiment 1

[0039] A large-scale virtual crowd simulation system, including a crowd behavior model simulation module, an environment processing module, and a behavior realization module, wherein: the environment processing module is used for data processing a static environment model, rendering a navigation grid, and creating an environment Model; the crowd behavior model simulation module is used to create a crowd perception model composed of regional perception and virtual senses, the crowd perception model obtains external information from the environment model, and provides information input for the behavior realization module to make behavior decisions; The behavior realization module is used to process the information input of the crowd behavior model simulation module, and judge the output behavior through logic.

[0040] The crowd behavior model simulation module includes a synthetic perceptron, an information filter and a decision-making behavior module, the synthetic perceptron i...

Embodiment 2

[0044] Based on embodiment 1, the simulation process of the present invention is:

[0045] The first step is crowd behavior model simulation, which is mainly to create a crowd perception model composed of regional perception and virtual senses, so as to provide technical support for the crowd to obtain external information and make behavioral decisions. When the crowd is in the virtual environment, how to perceive the surrounding environmental information, such as obstacles, pedestrians, elevators, fire locations, etc., and make corresponding feedback on the perceived information.

[0046] Perception is an agent's cognition of the environment and the behavior of providing conditions for its own behavior and decision-making. In general, crowd sensing needs to provide the following three functions:

[0047] 1. Regional awareness. The crowd judges the environment they are in through the perception and recognition of various objects in the environment. For example, whether the ...

Abstract

The invention discloses a large-scale virtual crowd simulation system. The system comprises a crowd behavior model simulation module, an environment processing module and a behavior realization module; the crowd behavior model simulation module is used for creating a crowd perception model composed of regional perception and virtual sense organs, and providing technical support for people obtaining external information and conducting behavior decision-making; the environment processing module is used for conducting data processing on a static environment model and rendering navigation grids; the behavior realization module is used for processing information input of a crowd and judging output behaviors through logic. According to the large-scale virtual crowd simulation system, in application, after a virtual crowd simulation technology is applied to an emergency drilling simulation training system of subway and high-speed railway platforms, the application of the technology can be extended to the aspects such as emergency exit design and emergency plan optimization of public buildings such as high-speed railways and subways through the accumulation of application experience and in-depth research, and the system has huge social and economic benefits.

Description

technical field [0001] The invention relates to simulation / simulation technology, in particular to a large-scale virtual crowd simulation system. Background technique [0002] With the rapid development of public transportation, high-speed rail, subway and other rail transportation tools have gradually become an important choice for people to travel. At the same time, in recent years, the safety and emergency response of public places have received widespread attention from the society. A more standardized emergency management system for public places such as high-speed rail stations and subway stations has also been gradually established. However, since its emergency handling process involves various departments and types of work such as dispatching, stations, crew members, drivers, and passenger transportation, as well as social emergency rescue agencies such as 110 and 119, it is difficult to organize emergency rescue and coordinate work is complicated. When an incident ...
