Virtual experiment platform system and method for crowd evacuation feature testing and drilling

Abstract

The invention relates to a virtual experiment platform system and method for crowd evacuation feature testing and drilling, in particular to a virtual experiment platform system used for crowd evacuation feature testing and evacuation drilling and based on a virtual reality technology and a microscopic analogue simulation technology, and relates to the technical field of computer virtual application. According to the virtual experiment platform system and method, the evacuation features of crowds under different scene conditions are tested through construction of a computer virtual environment. The virtual experiment platform method comprises the steps that firstly, a crowd evacuation model is built in a computer visual programming environment; secondly, the operation that movement of a controllable virtual leading actor in the crowd evacuation model is controlled through a computer input device is achieved; finally, various virtual evacuation scenes are achieved by changing the building structures and the visual fields of the crowds in the crowd evacuation model and leading an emergency product in. A testing experiment is conducted on a built virtual experiment platform in a participation mode, the evacuation features of the crowds on different scenes can be tested and analyzed, the virtual experiment platform can be applied to evacuation drilling and training when an emergency happens, and the virtual experiment platform system and method have the advantages that the crowd evacuation feature testing and drilling can be easy and can be repeated.

Description

Technical field [0001] The present invention relates to the field of computer virtual application technology, and specifically refers to a virtual experimental platform system based on virtual reality technology and microscopic simulation technology for personnel evacuation feature testing and evacuation drills in the field of public safety. Background technique [0002] In crowded public places, once an emergency occurs, it is easy to cause a crowded stampede accident, causing serious casualties. Therefore, measures to ensure the safety of evacuation in emergencies and improve the emergency level of public places are still urgent practical needs. In recent decades, in order to gain a deeper understanding of the dynamic characteristics of evacuation movements, researchers in different fields have used experiments and models to conduct detailed and in-depth exploration. Among them, the experimental method is the basis for revealing the rules of personnel movement behavior and evo...

Problems solved by technology

[0003] However, comparatively speaking, it is difficult for controllable experiments to create an emergency environment, and it is dangerous to carry out evacuation experiments under emergencies; although observation experiments can analyze the cases of incidents that have occurred, the conditions of personnel under emergencies can be obtained. evacuation characteristics, but it is difficult to quantify the impact of emergencies on evacuation movements
