VR virtual confrontation training system based on hierarchical behavior model

Abstract

A VR virtual confrontation training system based on a hierarchical behavior model comprises an environment construction unit, a simulation platform, a simulation resource library, an auxiliary planning unit, a virtual military strength generation unit, a guidance control unit and the like, and a model assembly subunit comprises an entity model assembly module and a behavior model assembly module. The behavior model assembly module realizes hierarchical behavior model assembly based on a hierarchical behavior model, the hierarchical behavior model assembly mainly comprises a brain decision model and a cerebellum action model, and the assembled behavior model performs intelligent decision mainly through analysis of a battlefield situation in combination with a behavior rule model in a simulation resource library, and generates a proper action plan, and driving the physical model of the simulation entity to respond to an action instruction by means of an execution mechanism, thereby completing the response of the virtual force to the battlefield situation. Common elements of the behavior model are abstracted, a universal behavior model system is constructed, and the behavior model structure is separated from specific contents, so that universal and standardized design of the behavior model is realized.

Description

technical field [0001] The invention relates to the field of virtual confrontation simulation training, in particular to a VR virtual confrontation training system based on a layered behavior model. Background technique [0002] As an important part of the virtual confrontation simulation, the main function of the agent is to enhance the authenticity of the virtual confrontation simulation and make the virtual confrontation closer to reality. At present, the virtual confrontation system adopts an integrated framework / method when constructing individual behavior models of agents, that is, each or each type of intelligent entity is used as the smallest unit to construct individual behavior models. The single agent behavior model constructed by the above framework / method has poor reusability, composability, and maintainability, and the coupling between the decision-making layer and the execution layer of the single agent behavior model is very strong. The single agent behavior...

AI Technical Summary

Problems solved by technology

[0004] 1. It will lead to the existence of a large number of "chimney" simulation systems, and each simulation system built is self-contained, and it is difficult to communicate and reuse each other;

[0005] 2. It will lead to a lot of repetitive design and development work, resulting in a lot of waste of manpower, material resources, financial resources, time and other resources;

[0006] 3. It will greatly reduce the efficiency of system development, increase the difficulty of development, and prolong the development cycle;

[0007] 4. It will lead to poor flexibility in system development and system maintenance, making it impossible to conveniently and flexibly carry out system development and system maintenance

For example, when one of the behavior logics changes, the entire behavior model of the agent needs to be modified, which greatly increases the difficulty of modification and the total amount of work.
