Problems solved by technology

[0002] At present, many ships will be overloaded during transportation, resulting in insufficient freeboard, and there will be safety hazards when the wind and waves are large and the ship turns. However, there is no method in the prior art that can effectively detect whether the freeboard of a sailing ship meets the requirements. Methods

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] like figure 1 As shown, a method for detecting ship navigation safety based on image recognition is characterized in that it includes:

[0040] S1. Obtain the top view of the sailing ship, and preprocess the obtained top view;

[0041] Firstly, aerial photography is used to obtain the top view of sailing ships, such as bulk carriers and container ships. Since it is difficult for the shooting equipment to be directly above the sailing ship during shooting, the captured image needs to be corrected. In addition, the image captured by the environment will have noise, so the image needs to be filtered, sharpened, and de...

Abstract

The invention discloses a ship navigation safety detection method based on image recognition, comprising the following steps: 1) obtaining the top view of the sailing ship in real time; 2) judging the type of the sailing ship according to the top view of the ship, and setting the freeboard regulation of the ship according to the judgment result 3) obtain the side view of the sailing ship in real time; 4) calculate the actual value of the freeboard of the ship according to the obtained side view of the sailing ship; 5) judge according to the type of ship obtained in step 2) and the specified value of the freeboard of the ship Whether the actual freeboard HG of the sailing ship meets the requirements for safe navigation. The invention monitors the height of the freeboard through an image recognition method to ensure the safety of the ship's navigation, can calculate in real time whether the freeboard of the ship meets the design requirements, grasp the safety status of the ship in real time, and provide assistance for safe navigation on water.

Description

technical field [0001] The invention relates to ship safety detection technology, in particular to a ship safety detection method based on image recognition. Background technique [0002] At present, many ships will be overloaded during transportation, resulting in insufficient freeboard, and there will be safety hazards when the wind and waves are large and the ship turns. However, there is no method in the prior art that can effectively detect whether the freeboard of a sailing ship meets the requirements. Methods. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an image recognition-based ship navigation safety detection method for the defects in the prior art. [0004] The technical solution adopted by the present invention to solve the technical problem is: a method for detecting ship navigation safety based on image recognition, comprising the following steps: [0005] 1) Obtain the top view of the sailing...
