【摘要】 高层体系结构(HLA)作为一门在计算机技术、网络技术和仿真技术的基础上发展起来的新技术,它一出现就立即受到军事训练和模拟作战等领域的广泛重视。本课题从研究高度逼真的虚拟海洋战场环境仿真系统的实际需要出发,提出基于HLA的分布式虚拟海洋战场环境仿真系统,并对其关键技术进行了深入研究。论文的主要工作有: 首先研究了虚拟海洋战场环境的系统组成。研究了合成虚拟海洋环境的设计与开发过程,研究了海底地形数据采集系统、视景数据库的生成过程以及地形和动、静态实体的三维建模技术。 其次在学习视景仿真开发软件MultiGen Creator和Vega的基础上,对建立模型的关键技术进行了研究,并建立了地形模型和舰艇模型。针对实际需要,利用粒子系统实现了对雨雪等气象环境的模拟,利用Vega的路径和导航器工具实现了物体自动漫游的功能。 深入研究高层体系结构的内容和技术原理。HLA的核心思想是互操作和重用,它解决了仿真系统的灵活性和可扩充性问题,减少了网络冗余数掘。 最后,根据实际需要,设计了了一个基于高层体系结构的小型分布式虚拟海洋战场环境仿真系统,给出了使用VR-Link的分布式虚拟海洋战场环境系统的实现过程及双通道、自由视点、场景的记录与回放等技术的实现方法。更多还原

【Abstract】 High Level Architecture (HLA) is a new technique developing from computer technique, network technique and simulation technique. Once it appears, it has been paid much attention in the areas of military training and battle simulating. Considering current development of the simulation of virtual ocean battlefield environment, this dissertation put forward Distributed Virtual Ocean Battlefield Environment based on High Level Architecture (HLA). And key technologies have been studied. The main works are as follows:Firstly, the configuration of Distributed Virtual Ocean Battlefield Environment was studied. Then this dissertation studies the design and development process of synthesized virtual ocean environment, including the method of the data collection system of seabed terrain, the data source and development process of scene database and the 3D modeling method of terrain, dynamic entities and static entities.Secondly, the key modeling technologies was studied according to the VR development software MultiGen Creator and Vega. Then the models of terrain and submarine were built. And then, this dissertation gives a method to simulation rain and snow. This dissertation also studies how to realize auto roaming by using Navigator tool and Path tool in Vega.Then this dissertation studies the components of HLA. The kernel thoughts of HLA are interaction and reuse. The technique of HLA will help to solve the problem of agility and expansion in simulation system. And it will help to reduce the network redundancy data.In the end, using VR-Link, the system of Distributed Virtual Ocean Battlefield Environment based on HLA was realized. This dissertation discusses the process of the realization. And the technologies of dual channel, free eye-point and scene record were given.更多还原
