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.
