【摘要】 介绍了基于AIS的船舶三维显示与避碰系统的功能特点和关键技术.通过研究多分辨率地形绘制技术和海浪运动模型等虚拟现实技术,实现三维海床的实时绘制和逼真海面的模拟生成.通过对AIS报文解析,获取周边船舶的位置和态势信息,最终实现了海床、海面和周边船舶组成的三维场景一体可视化;并通过在逼真的海上三维场景上叠加显示AIS信息和避碰辅助决策信息,更直观有效地保障了船舶航行安全.更多还原

【Abstract】 This paper introduces the function characteristics and key technology of AIS based vessel three-dimensional display and collision avoidance system.The research on the VR technologies such as multi-resolution terrain rendering technology and the ocean wave movement model created the real-time rendering of three-dimensional seabed grid and the simulating of dynamic ocean wave.The nearby vessel position and situation information obtained from AIS message analysis ultimately realized the display of integrated visualization of three-dimensional scene composed by seabed,sea surface and circumjacent vessels,and the AIS information and collision-avoidance assistance decision information superimposesly showed on the vivid three-dimensional scene display directly guaranteed the vessel safety.更多还原
