内河船舶航行环境视景三维仿真

3D Visual Scene Simulation of Inland Waterway Navigational Environment

基于航海仿真的发展方向和发展需求,为增加练习海域并同时提高仿真精度,以内河船舶航行环境三维建模仿真为研究对象,分析了内河船舶航行环境视景的组成要素,将其主要划分为地形地貌、水面及近岸陆域物标两大模块,并以视景仿真领域3D MAX、Multigen Creator等主流软件对其进行三维建模。在VC++环境下,以开源软件OpenSceneGraph(OSG)为驱动平台,对内河船舶航行环境视景模块三维模型进行了数据融合,同时以细致的渲染来加强模拟的真实感。仿真显示:所构建的内河船舶航行环境三维模型具有较高的精度,场景驱动具有逼真的效果,能够满足航海仿真的要求并应用于大型船舶操纵模拟器建设。

Based on the development directions and requirements of navigation simulation,3 Dvisual simulation of inland waterway navigation environment was taken as the research object,in order to expand the practice area and improve the simulation accuracy at the same time.Elements composing the scenery of inland waterway navigation environment were deeply analyzed and divided into two categories：topographic and geomorphic features,surface and offshore targets.The mainstream software in scene simulation field such as 3 D MAX and Multigen Creator were adopted for 3 D modeling of the composing elements.Under the environment of VC＋＋,the open source software OpenSceneGrap（OSG）was chosen as the driving platform to realize data fusion of 3 D model of inland waterway navigation environment and strengthen simulation authenticity with meticulous rendering.Simulation shows that the constructed 3 D models of inland waterway navigation environment are of higher precision,and its driving scenario is of verisimilitude,which can meet the navigation simulation requirements and can be recommended for development of large ship handling simulator.
