The invention discloses a ship navigation behavior identification method and system, electronic equipment and a storage medium, and relates to the technical field of ship monitoring or other related technical fields, and the method comprises the steps: obtaining the ship position data of a target ship collected by N signal sources, carrying out the data fusion of the ship position data of the target ship under different signal sources, and obtaining a ship navigation behavior identification result; obtaining fused ship position data; in each space-time area of the target ship in navigation, optimal ship position data is screened out from the fused ship position data, and a navigation track of the target ship is generated based on the optimal ship position data; and inputting the navigation trajectory of the target ship into a pre-constructed normal ship trajectory model, and calculating to obtain trajectory feature similarity between the navigation trajectory of the target ship and the navigation trajectory of a normal ship so as to identify a normal navigation behavior or an abnormal navigation behavior of the target ship. The technical problem that the ship navigation behavior cannot be accurately identified in the prior art is solved.
本发明公开了一种船舶航行行为的识别方法及系统、电子设备及存储介质,涉及船舶监测技术领域或其他相关技术领域,其中,该方法包括:获取由N个信号源采集的目标船舶的船位数据,将目标船舶在不同信号源下的船位数据进行数据融合,得到融合后的船位数据;在目标船舶航行的每个时空区域内,从融合后的船位数据中筛选出最优船位数据,并基于最优船位数据生成目标船舶的航行轨迹;将目标船舶的航行轨迹输入到预先构建的正常船舶轨迹模型,计算得到目标船舶的航行轨迹与正常船舶的航行轨迹之间的轨迹特征相似度,以识别目标船舶的正常航行行为或异常航行行为。本发明解决了相关技术中无法准确地识别船舶航行行为的技术问题。
