Embodiment Construction

[0017] The specific implementation of the method and system for correcting the ship's navigation track of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] refer to figure 1 , figure 1 Shown is the flow chart of the method for correcting the ship's navigation track of an embodiment, including the following steps:

[0019] S10, acquiring track points recorded by the ship automatic identification system that the ship sails through; wherein, the track points are coordinate points indicating the position of the ship sent by the ship-borne equipment to the shore-based equipment;

[0020] The above steps, based on the data recorded by the AIS system, obtain the track points passed by the ship; the track can refer to the connection between two adjacent track points in time order, which is used to approximately represent the ship at a certain track point The path of moving to the next track point; the ship’s navigation tr...

Abstract

The present invention relates to a correction method and system of a ship sailing trajectory. The method comprises a step of obtaining ship sailing trajectory points recorded by a ship automatic identification system, wherein the sailing trajectory points are coordinate points which express the positions of a ship sent to shore-based equipment by ship-borne equipment, a step of identifying the noise in the sailing trajectory points according to the coordinate information of a sailing trajectory, and determining the real sailing trajectory points and noises in the sailing trajectory, a step of eliminating the noises in the sailing trajectory, and correcting the sailing trajectory according to the real sailing trajectory points to obtain the corrected sailing trajectory of the ship. According to the scheme of the invention, the correction of the sailing trajectory of the ship is realized, the condition of abnormal ship sailing trajectory in AIS system information can be corrected, and the more real and effective available sailing trajectory can be provided.

Description

technical field [0001] The invention relates to the technical field of navigation detection, in particular to a method and system for correcting a ship's navigation track. Background technique [0002] Relevant detection technologies in the navigation process have a crucial impact on route planning, water transportation capacity scheduling, and route safety. It has a significant impact on production and life in related fields. [0003] Ships navigating in waters generally determine the navigation trajectory by installing the Automatic Identification System (AIS system for short). The AIS system is composed of shore-based (base station on land) equipment and ship-borne equipment. Digital navigation aid system and equipment integrating modern communication technology, computer technology and electronic information display technology. The system sends the ship's navigation information to the outside world by means of broadcasting, etc., so that its navigation route can be obt...
