真实海洋环境视景仿真技术研究

真实海洋环境的视景仿真技术一直是虚拟现实仿真技术的重要研究方向之一。针对此课题,系统研究了三维海洋环境的组成和环境建模技术,从二维电子海图中直接获取海洋地理环境数据,作为虚拟海洋环境视景仿真的数据基础,采用基于Delaunay算法的三维数字地图地形建模方法,将三维地形数据转化为可以直接进行三维建模的ded文件。实验演示了海洋地理信息三维模型库的构建方案、模型示例及三维虚拟海洋环境的实现,取得了逼真的仿真效果。

Research of True Ocean Environment Visual Simulation Technology

The visual simulation technology of true ocean environment is one of the most important research aspects in virtual reality simulation technology. Aiming at this problem, the constitution of three dimension ocean environment and environment modeling technology was studied systematically, and the ocean geography environment information was obtained from two dimension electronic chart directly, which was the data base of virtual ocean environment visual simulation. The 3-D digital map modeling method based on Delaunay arithmetic was used, and then the 3-D landform data was translated into the ded file which could serve for the data of landform 3-D modeling. The design project and example model of ocean geographic information 3-D model library was shown, and the true ocean scene of 3-D virtual environment visual simulation was displayed, too, which achieved living simulation effect.
