船舶机舱虚拟现实仿真系统的实现方法

Realization Methods of Marine Engine Room Visual Simulation System

详细介绍了运用MultiGen Creator和Vega等软件实现具有VR特征的船舶机舱虚拟现实仿真系统的方法,其中主要有:利用Creator进行三维建模过程中的场景数据库层次结构技术、实例化技术、外部引用技术、纹理映射技术和实时视景生成技术等;利用Vega实现船舶虚拟机舱的自动漫游和手动漫游方法以及漫游过程中的碰撞检测技术等;首次实现了与船舶轮机模拟器之间通信,实现虚拟机舱与轮机模拟器之间的相互操作,保持虚拟场景中虚拟仪表、虚拟指示灯等部件的状态与船舶轮机模拟器相应部件的状态一致。开发出的船舶机舱虚拟现实仿真系统,建立了逼真的船舶机舱虚拟场景,实现了人在虚拟机舱环境中的漫游,可以对虚拟场景中主要运动部件的驱动,是对现有船舶轮机仿真器有益的补充,有利于提高轮机员培训的教学质量。

The methods of developing the marine engine room visual simulation system were proposed which had VR characteristics using software named Multigen Creator and Vega etc. The main technology methods are as follow： the scene database, instance, external reference, texture in the process of modeling visual marine engine room using Multigen Creator; the methods of developing two walkthrough modes： controllable walkthrough and automatic walkthrough using Vega; the technology of collision check-up in roaming marine engine room. Communication between visual simulation system and Marine Engine Room Simulator were established, The marine engine room virtual simulation system built the visual 3D scence of marine engine room and students could roam and do some operations through monitors and operation equipments. The virtual simulation system is a beneficial supplement of marine engine room simulator and also improves the seaman training quality.
