    摘要:

    针对船舶操纵模拟中的三维视景仿真的特点,开展船舶操纵模拟器中关于上海洋山港港区三维视景仿真的研究。以Google Earth提供的电子地形图像为基础,经过等高线和矢量化方法的处理,生成数字高程模型(Digital Elevation Model, DEM),并利用Multigen Creator建立直观的上海洋山港港区三维地形模型,再利用Vega的三维视景渲染功能对其进行渲染和驱动。根据该方法建立的上海洋山港港区三维视景模型库在模型精细度、逼真度和实时运算等方面,都能满足船员实操练习所需的条件。

    Abstract:

    According to the characteristics of 3D visual simulation in ship handling simulation, the research on 3D visual simulation in Yangshan port area in Shanghai is carried out. Based on the electronic terrain image provided by Google Earth, Digital Elevation Model (DEM) is generated through the processing of contour line and vectorization method, and an intuitive 3D terrain model of Yangshan port area in Shanghai is established by Multigen Creator, which is then rendered and driven by Vega's 3D visual rendering function. Based on contour map and vectorization method, the method of 3D visual model is studied. According to the method, the 3D visual model database of Yangshan port area in Shanghai can meet the requirements of crew's practical practice in terms of model precision, fidelity and realtime operation.
