英文摘要：

To overcome the disadvantages of current ship dynamic surveillance systems so as to improve the intuition of the surveillance flatform, the 3D visualization technology is employed to intuitively manage the ships in 3D sea space. The 3D sea geographic environment is automatically created based on electron-ic chart data. The land topography is seamlessly integrated with the 3D sea geographic environment by the OsgEarth-based global scene management platform. The pyramid technology is used to effectively organize image data so as to build the global 3D ship dynamic surveillance system. The effectiveness of the pro-posed method is analyzed quantitatively and qualitatively through experiments. The proposed method pro-vides a new idea for the global 3D scene management of ship dynamic surveillance.
