港口水域电子海图数据快速检索算法及应用

Research of Algorithm and Application of Chart Data Quickly Retrieval in Port Area

针对港口水域复杂且船舶密度大,容易发生船舶搁浅及碰撞事故的问题,基于船舶智能操控(SIHC)仿真平台,对S-57海图数据进行再组织,根据搁浅触礁预警模型建立海图检索区域,采用动态拾取海图数据的方法,设计海图数据快速检索算法,借助SIHC仿真平台进行算法的仿真实验验证。结果表明,该算法实现了船舶对静态碍航物的实时预警。

In port area,the environment is complicate and the vessel destiny is large. Based on the simulation platform of ship intelligent handle and control（ SIHC）,the S-57 chart data was reorganized. The chart retrieve area was constructed based on the model of ship early warning of grounding. The dynamic pick-up to get the electronic chart data was utilized to design the algorithm of rapidly retrieval of electronic chart data. The simulation result showed that the algorithm can achieve the real-time warning of static obstruction.
