船舶航道信息管理系统的可视化数据检索研究

Research on visual data retrieval of ship channel information management system

当前船舶航道信息管理系统在对航道数据检索的过程中出现信息混乱,存在更新周期慢、成本高昂等缺点难以直观准确的显示航道图像。基于上述问题对航道信息管理系统的可视化数据检索方法进行研究。结合GIS系统对可视化数据分析方法对船舶航道信息可视化信息管理和检索系统进行设计,以便快速有效的处理航道遥感图像信息。最后通过仿真实验证实该方法能够精准的对航道边缘信息进行显示,从而实现对航道的动态管理。实验结果证实该系统性能可靠,效果良好,能够有效提高航道管理的工作效率,具有较高的实用价值。

At present, the ship channel information management system is confused in the process of navigation channel data retrieval, and it is difficult to display navigation channel images intuitively and accurately because of the shortcomings such as slow update cycle and high cost. Based on the above problems, the visual data retrieval method of the channel information management system is studied. The visual information management and retrieval system of shipping channel information is designed by means of GIS data analysis method in order to deal with the remote sensing image information of shipping channel quickly and effectively. Finally, the simulation experiment proves that this method can accurately display the information of the channel edge, so as to realize the dynamic management of the channel. The experimental results show that the system is reliable and effective, and it is of high practical value to improve the efficiency of channel management.
