面向船舶动态监控的全球3D场景管理关键技术

Key technique of global 3D scene management for ship dynamic surveillance

为克服目前船舶动态监控系统的不足,提高监控平台的直观性,提出使用3D可视化技术实现船舶在3D海域空间的直观管理.根据电子海图数据自动建立3D海域地理环境;利用基于Osg Earth的全球场景管理平台无缝融合陆上地貌与3D海域地理环境;利用金字塔技术有效组织影像数据,构建全球3D船舶动态监控系统.通过实验定量和定性分析了该方法的有效性,为面向船舶动态监控的全球3D场景管理提供了新的思路.

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.
