为使姿态数据能够直观、逼真地展现船舶运动状况，利用串口通信、Creator建模和OpenSceneGraph（OSG）场景管理技术，实现船舶姿态三维可视化.采用OSG三维渲染引擎创建三维场景，利用解析捷联惯导系统串口输出的姿态数据来控制Creator建模软件建立的船舶模型，并创建场景漫游器，实现从任意位置观察船舶运动的目的.以VisualStudio2008和OSG场景管理软件为开发平台，完成船舶运动姿态三维显示系统的开发，将船舶运动姿态实时、直观地显示给驾引人员，为船舶姿态显示提供了一种新的方法，并可应用到船舶综合船桥系统中.
Abstract
In order to improve the perceived accuracy and real-time of obtaining attitude data, the paper takes advantages of serial communications, Creator modeling and OpenSceneGraph (OSG) scene management technology to achieve three-dimensional visualization of ship attitude. The paper uses OSG 3D rendering engine to create a 3D scene, and the attitude data analyzed from SINS through serial ports is used to control ship model created by Creator modeling software, and to create scene roaming to realize the observation of ship model from any position. Using VisualStudio2008 and OSG scene management software development platform, the paper completes the development of three-dimensional display system of ship attitude. It visually real-time demonstrates ship attitude to deck officer and pilot, which provides a new method for ship attitude display, and it can be used in integrated bridge system as well.
