基于元模型的战场环境多分辨率建模

Multi-resolution modeling of battlefield environment based on meta-model

为了满足复杂仿真系统对战场环境模型不同分辨率的要求,解决不同分辨率环境模型的转换问题,给出了基于元模型的多谱线分辨率战场环境建模方法.该方法首先对将要建模与仿真的战场环境进行分解,得出战场环境模型的组成部分及战场环境与军用仿真实体的5个交互类别,然后通过战场环境的元建模参考框架,给出了战场环境元模型最基本的组成要素,利用递阶层次的元模型来构造各个环境模块,最后使用BNF来实现战场环境的元模型,通过合并元模型的相同节点来实现不同层次细节和详细层度的多谱线分辨率环境模型,也保证了战场环境模型的语法一致性.

A method based on meta-model is proposed to meet the spectral multi-resolution model transformation with the increasing requirement of battlefield environmental multi-resolution model. At first the battlefield environment to be simulated is disaggregated to variable factors, and the makeup of battlefield environment model is listed as the 5 interface classes between battlefield environment and the military simulation entities. Then these factors are constructed by hierarchical meta-models according to the reference framework of battlefield environment meta-modeling. At last, Backus Naur Form（BNF） is used to implement the environmental meta-models and spectral multi-resolution models are implemented by aggregating the same node of these meta-models. The consistency is maintained between these battlefield environmental models.
