摘　　要：内河航道水深、地形随季节变化较大,很大程度上制约了船舶安全高效航行.针对这一问题,提出内河航道虚拟仿真系统,真实展现航道地形和水深情况,为船舶航行提供有效辅助.研究以航道测量数据的处理为基础,主要进行地形高程数据提取、地形数据格网化,以及BJ-54坐标转换,并结合Ogre 3D引擎技术,实现航道三维可视化和适合船舶航行航道的划分.应用结果表明,航道三维效果逼真,具有较强的沉浸感,仿真系统能够为船舶正确指出安全航道,满足内河航运需求.Shipping safety and efficiency was largely restricted by the change of inland waterway depth and topography,the navigational requires extensive experience in complex navigational operations.To provide auxiliary for sailing ship,the virtual inland waterway simulation system was presented.The system mainly research on channel measurement data processing,including elevation data extraction and interpolation,terrain data grid and BJ-54coordinate conversion.Through study on the key technology of OGRE and combined with the converted data and the 3Dengine,3-dimensional riverbed and suitable channel for ship was generated.Experimental results show that the solution for building virtual inland waterway simulation system has a strong sense of reality and immersion,and the simulation system can differentiate safety fairway for navigation correctly,making sailing more secure and efficient.
