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. The method comprises the following steps: step 1, acquiring a navigation ship top view in real time; step2, judging the type of a navigation ship according to the ship top view, and setting a ship freeboard specified value according to a judgment result; step 3, acquiring a side view of the navigation ship in real time; step 4, calculating the actual value of the ship freeboard according to the obtained side view of the navigation ship; and step 5, judging whether the actual freeboard HG of the navigation ship meets a safe sailing requirement or not according to the ship type obtained in the step 2 and the ship freeboard specified value under the type. The freeboard height is monitored through animage recognition method, so that the ship navigation safety is ensured, whether the freeboard meets the design requirement or not during ship navigation can be calculated in real time, the safety state of the navigation ship is mastered in real time, and assistance is provided 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...
