Embodiment Construction

[0047] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0048]With the rapid development of the shipping industry, decked ships have become more and more common in the field of maritime traffic. However, in the process of identifying decked ships, due to factors such as long distances, unstable routes, and difficult positioning The cost of ship identification is relatively high, so the current method of determining deck ships is mainly to det...

Abstract

The invention provides a fake-licensed ship identification method and system, and the method comprises the steps: obtaining a ship automatic identification system (AIS) data sequence belonging to the same ship identification information, arranging the AIS data in the AIS data sequence according to the receiving time, wherein the AIS data comprise dynamic information; based on dynamic information contained in AIS data in the AIS data sequence, determining a plurality of dynamic trajectory branches, and determining the category of each dynamic trajectory branch, wherein the category comprises fake-licensed ship branches; if it is judged that the dynamic trajectory branches include fake-licensed ship branches and the number of the fake-licensed ship branches is larger than 1, determining that the ship identification information is identification information of the fake-licensed ship. According to the fake-licensed ship identification method provided by the invention, external factors such as weather and distance can be overcome, the fake-licensed ship can be effectively identified, a perfect ship number identification monitoring system does not need to be erected, the identification cost of the fake-licensed ship is reduced, and an AIS data sequence is adopted, so that the identification accuracy of the fake-licensed ship is ensured.

Description

technical field [0001] The present invention relates to the technical field of transportation, in particular to a method and system for identifying decked ships. Background technique [0002] In the field of land transportation, some users choose to use deck cards in order to avoid being punished for illegal driving of their own vehicles, that is, deck cards appear. Similarly, in the field of maritime traffic, the phenomenon of decked ships is also relatively common. [0003] However, due to the special traffic environment at sea, there are many inconveniences in the detection of decked ships, such as: 1) The weather environment and distance factors will cause the ship number to be easily recognized like a license plate; Ship number identification monitoring system, etc. [0004] Therefore, there is an urgent need to provide an effective deck ship identification method. Contents of the invention [0005] The present invention provides a method and system for identifying...
