Virtual reconstruction of ship trajectory based on multimedia technology

对舰船轨迹的虚拟重构主要包括了对舰船模型和舰船尾流的三维视景仿真重构,为了提高舰船轨迹虚拟重构的逼真度,在多媒体视觉下,提出一种基于Vega prime和Multigen Creator建模的舰船轨迹虚拟重构技术,对获取的舰船船体数据和尾流数据进行数据加载和信息编译,在虚拟场景中根据场景状态信息和渲染指令进行海洋场景、舰船模型和尾流气泡模型的绘制。采用不规则三角网分割方法实现分区域三维重构和图像处理,实现舰船轨迹虚拟重构优化。仿真结果表明,采用该方法进行舰船轨迹虚拟重构和视景仿真的逼真性较好,图像渲染能力较强,具有较好的视觉效果。

The virtual reconstruction of the ship trajectory including 3D scene simulation and reconstruction of the ship model of ship wake, in order to improve the fidelity of virtual ship trajectory reconstruction, in view of multimedia, this paper presents a virtual reconstruction technique of Vega prime and Multigen ship trajectory based on Creator modeling, data loading and compiling information on access the ship hull data and wake data, ocean scene in virtual scene scene according to the state information and rendering commands, rendering model and model of ship wake bubbles. The segmentation method based on triangular irregular network to realize regional 3D reconstruction and image processing, realize the virtual reconstruction of ship trajectory optimization. The simulation results show that by using this method ship trajectory reconstruction and virtual reality scene simulation better image rendering ability, has a better visual effect.
