Embodiment 1

[0053] refer to figure 1 , the present embodiment provides a method for linkage tracking of ships, including:

[0054] S100. Receive the AIS signal reporting information of the ship to be tracked, where the AIS signal reporting information includes the reporting position;

[0055] S200. According to the position reporting information of the AIS signal, insert an interpolation position into the position reporting position using a fitting interpolation method, and form the navigation track of the ship to be tracked by fitting the position reporting position and the interpolation position;

[0056] S300. Track the ship to be tracked according to the trajectories of the ship to be tracked.

[0057] On the basis of the above solution, the AIS signal reporting information also includes: reporting time, speed, course and heading.

[0058] Among them, the reporting time and speed are the information for calculating the predicted position of the ship to be tracked according to the na...

Embodiment 2

[0070] On the basis of the above examples, refer to image 3 , when tracking the ship to be tracked according to the track of the ship to be tracked,

[0071] S311. Acquire an image containing the ship to be tracked;

[0072] S321. Using an image recognition method to recognize the recognition position of the ship to be tracked in the image;

[0073] S331. According to the identified position and the predicted position of the navigation track, determine whether a deviation occurs in the tracking unit;

[0074] S341. If the tracking unit has a deviation, calculate the deviation angle of the tracking unit, and correct the deviation angle of the tracking unit;

[0075] S351. If no deviation occurs in the tracking unit, do not correct the tracking unit.

[0076] Wherein, the tracking unit may be a device such as a pan / tilt.

[0077] Wherein, the predicted position refers to the position of the ship to be tracked on the sea surface at the next time point predicted according to ...

Embodiment 3

[0121] This embodiment provides a device for linkage tracking of ships, which is used for the operation of the method for linkage tracking of ships described in Embodiment 1 or Embodiment 2, including:

[0122] The signal receiving unit is used to receive the AIS signal reporting information of the ship to be tracked, and the AIS signal reporting information includes the reporting position;

[0123] The signal processing unit is used to insert an interpolation position into the position reporting position by using a fitting interpolation method according to the position reporting information of the AIS signal, and form the navigation track of the ship to be tracked by fitting the position reporting position and the interpolation position;

[0124] A tracking unit, configured to track the ship to be tracked according to the navigation track of the ship to be tracked.

[0125] On the basis of the above solution, the AIS signal reporting information also includes: reporting time,...

Abstract

The invention provides a method and device for carrying out linkage tracking on a steamship, electronic equipment and a storage medium, and aims to solve the problem that in the prior art, a tracking unit cannot accurately track the steamship only through AIS signal position reporting information. The method for carrying out linkage tracking on the steamship comprises the following steps: receiving AIS signal position reporting information of the steamship to be tracked; according to the AIS signal position reporting information, adopting a fitting interpolation method to insert an interpolation position in a position reporting position, and forming a navigation track of the ship to be tracked by the fitting position reporting position and the interpolation position; and tracking the to-be-tracked steamship according to the navigation trajectory of the to-be-tracked steamship. The device for carrying out linkage tracking on the steamship comprises a signal receiving unit, a signal processing unit and a tracking unit. According to the invention, the position reporting position and the interpolation position are fitted by using the fitting interpolation method to form the navigation trajectory of the to-be-tracked steamship, so that the tracking unit can accurately and smoothly track the to-be-tracked steamship according to the navigation trajectory.

Description

technical field [0001] The disclosure belongs to the technical field of ship tracking, and in particular relates to a method, device, electronic equipment and storage medium for joint tracking of ships. Background technique [0002] Automatic Identification System (AIS for short) refers to a new type of navigation aid system applied to maritime security and communication between ships and shores, and between ships and ships. With the mandatory conventions of the International Maritime Organization (IMO), AIS equipment has been widely used. The signal sent by the AIS of the ship can provide static information such as the name, length, width, and type of the ship, as well as the ship's position, course, Dynamic information such as heading and speed. [0003] When the ship is sailing, its movement is a continuous process, but the AIS signal position reporting of the ship is a discrete process, that is, the AIS equipment of the ship sends out an AIS signal position at a certain...
