Problems solved by technology

[0003] In the prior art, crowd simulation models can be divided into macro-models and micro-models. At present, crowd simulation models for specific application scenarios are generally modified locally on the basis of the above-mentioned basic simulation models. The individual rules of the application scenario, but the limitation of this method is that it hardly considers the influence of information exchange between individuals in the group on individual behavior. Taking the group in the emergency evacuation process as an example, the information exchange between individuals in the group is directly Affects how individuals respond to different events, and failure to account for these issues can make simulation models inaccurate

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the group simulation method provided in the embodiments according to the present invention will be described below with reference to the accompanying drawings.

[0028] Group simulation appeared earlier in computer graphics. After years of development, group simulation has also combined the technical content of many other disciplines, from the macroscopic simulation model with agglomeration as the main feature to the microscopic simulation model with individual characteristics as the object. , swarm simulation is widely used in many fields, especially in the field of safety science, swarm simulation can simulate emergency evacuation, for example, to judge whether the design of buildings is reasonable or to choose the optimal path for crowd evacuation, etc.

[0029] The inventors have found through research that the existing models rarely take into account the information exch...

Abstract

The invention relates to a group simulating method. The group simulating method comprises the following steps: establishing an information communication model among groups and marking information; calculating different path cost values and acquiring a minimal cost path by utilizing information marks; establishing an individual behaviour decision model according to the minimal cost path and selecting a path.

Description

technical field [0001] The invention relates to the technical field of group simulation, in particular to a group simulation method. Background technique [0002] With the development of science and technology, the level of computer simulation technology has also been significantly improved. How to establish accurate and effective simulation models has become a research hotspot in many simulation fields. For example, the simulation modeling of sports groups has become one of the research focuses of virtual reality technology in recent years because it can be widely used in many scenarios such as crowd evacuation, passenger flow management, architectural design, urban planning, and emergency plans in public places. [0003] In the prior art, crowd simulation models can be divided into macroscopic models and microcosmic models, etc. Currently, crowd simulation models for specific application scenarios are generally modified locally on the basis of the above-mentioned basic sim...
