摘要
为了提高大型舰船横穿桥梁时,其远程监测的有效监控范围,设计提出了一种基于舰船轨迹分析的新型安全性远程监测方法。建立固定坐标系和舰船航行坐标系,根据舰船航行重心G,明确船舶航迹及船位,通过三维点云数据提取技术,提取航迹特征值,根据聚类计算结果,求取船舶未来过桥时的有效路径及间距,建立远程传输通路和后台分析模块,通过知识库内预设的逻辑处理分析程序,对当前船舶轨迹特征信息和预设轨迹特征信息进行测评,实现舰船安全性远程监测。实验数据显示,该方法在顺向风流环境下,对舰船安全性远程监测有效监控范围提高了29%,说明该方法确实可以提高远程监控的有效监控范围,具有明显优势性。
in order to improve the effective range of remote monitoring for large ships crossing a bridge, a new security remote monitoring method based on ship trajectory analysis was proposed. Establish a fixed coordinate system and the ship sailing, according to the ship sailing center of gravity G, clear ship track and position, using three-dimensional point cloud data extraction techniques, to extract the characteristic values of track according to the clustering results, calculate the ship cross the bridge when the future of effective path and spacing, establishing remote transmission channel and the background analysis module, through the analysis of the logic to handle knowledge storehouse the preset program, to the current ship trajectory characteristic information and the preset trajectory characteristic information for evaluation, implement safety remote monitoring. Experimental data show that this method can improve the effective monitoring range of ship safety remote monitoring by 29% under the condition of forward airflow, which shows that this method can indeed improve the effective monitoring range of remote monitoring and has obvious advantages.
