摘要
船舶动力装置系统仿真是仿真技术应用于船舶的一个热点，通过对特定船舶动力装置系统进行建模和仿真，能够在避开实船试验和推进主机台架试验情况下，获得动力装置相关数据，实现动力系统的运行监控与测试。目前很多研究机构也展开了相应领域的可视化研究，但是大多是基于特定软件进行的研究，如Vega等，使研究成本相应提高，而且二次开发困难,使用盗版软件会使开发系统不稳定，很多功能不能使用，又不可能进行二次开发，所有这些情况已不能满足现代虚拟现实可视化开发的要求。
本文借助与目前应用越来越广泛的三维渲染引擎OpenSceneGraph(OSG)来开发基于船舶驾驶的可视化系统。OSG以其开源特性在虚拟社区迅速传播开来，受到了越来越多的开发者的青睐，应用领域也越来越广泛。视景的显示部分全部依靠OSG的渲染功能显示输出。本课题研究的是船舶的动力装置运动可视化仿真，动力装置的仿真使用Matlab软件，借助windows下VS2005软件开发平台，利用C++语言来管理仿真的运行与仿真运算，数据的存储和读取是利用SQL 2000数据库。首先调用Matlab软件，计算出仿真结果后存入SQL数据库，前台显示则是利用OSG强大的渲染功能，包括动态海洋的渲染，港口模型的显示，运动船舶的渲染等等都放在前台机器上来完成，这样就把大量的工作内容分配到两台计算机里运行，可以使单机配置相对较低，减少开发费用。
海面部分采用的是网络上王锐的模拟水面工程，港口则是模拟我国天然深水港口洋山港，按照比例模拟的方法建立模型，特征建筑为东海大桥。船舶则是采用三大船型之一的集装箱船为主。更确切的说本课题模拟了船舶的离、靠泊操作。
显示部分主要分为键盘驱动漫游和船舶读取数据自动运行两部分，漫游操纵主要利用OSG交互类osgGA库，文中很多类都是继承自此类库。此外，要实现驾驶效果，还设置了视点跟随效果，漫游和自动运行都设置了视点跟随。
本课题具有较强是实际使用意义，特别是以第一人称角色漫游，在完善模型的基础上，可以后续开发出手柄操作和数字手套操作等交互手段，这样可以浏览一些平时在学校和实验室很难看到的大型船厂或船舶，使研究者和学习者都能够对自己所学领域有一个更加感性的直观认识。

Abstract
Simulation technology has been applied to ship for many years, and marine power plant system simulation is a hot point of it. By the simulation of a particular model of ship power plant system, we can get the related data of this power plant system, we can achieve power system operation control without the real ship's propulsion test and bench test. At present many research institutes have launched the corresponding areas the visualization of study, but mostly based on a specific software research, such as Vega, so as to make research costs rise accordingly, and the secondary development difficulties. That has cannot satisfy the modern virtual reality visualization development requirements already.
This article based on the currently used more widely with the 3D rendering engine OpenSceneGraph (OSG) and development of ship's visualization systems. OSG has been spread quickly with its open source characteristics in virtual community, influenced more and more developers and its application fields are more and more widely. Visual’s display parts all depend on OSG rendering function. This topic’s research is the power unit of the motion simulation visualization, use Matlab software to simulation the power device, with the Windows under VS2005 software development platform, using c++ language to management simulation of operation and the simulation, the data storage and reading is to use SQL 2000 database. First invoking the Matlab software, compute simulation results then write to SQL database, the foreground to show is using OSG powerful rendering functions, including dynamic Marine rendering, port model shows, sports ship rendering etc are all on the front desk machine to finish. Thus put a lot of work content distribution to two computers to operate, also can make the single configuration relatively low, and reduce development costs.
The sea what we used is the Water project which relatively popular in internet by Wangrui, the port is copied natural deep water port in China yang Shan port, according to the proportion of the real model, the characteristic construction method is Donghai bridge.
Display section are mainly divided into the keyboard drive roaming and ship read data automatically run two parts, roaming manipulation using OSG mainly osgGA interaction class library, this article’s many classes are inherited from this. In addition, in order to meet the driving effect, still set a viewpoint follow effect, roaming and automatic operation also set the viewpoint to follow them.
This topic has a strong meaning in actual use, especially in the first person role in improving roaming, based on the completed model, we can the follow-up developed handles and digital gloves interactive methods, and can follow-up developed handles and digital gloves interactive methods, base on the operation that we can browse some large shipyards or ships which is difficult to see in schools and LABS. The researchers and learners are able to have a more sensible intuitive understanding in their learned domains.
Key words： Power plant, OSG, multi-channel, viewpoint follow..
