Embodiment Construction

[0049] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following technical solutions in the present invention are clearly and completely described. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0050] see figure 1 , the method for evaluating the strike effect of a target ship based on jet edge analysis and strike deviation feedback of the present invention mainly includes the following steps:

[0051] Step 1: Use the photoelectric head to collect image information.

[0052] Step 2: Process the video image information through a jet segmentation model to extract jet contours and ship contours. Specifically, in order to achieve the purpose of real-time p...

Abstract

The invention discloses a ship hitting effect evaluation method based on jet flow edge analysis and hitting deviation feedback. The ship hitting effect evaluation method comprises the following steps of S1, collecting the video image information through the photoelectric holder equipment; S2, processing the video image information through a jet segmentation model, and extracting a jet contour and a ship contour; S3, judging whether the jet flow striking exists or not based on an extraction result, and if no jet flow exists, returning to the step S2; if the jet flow exists, entering S4; S4, judging whether the jet flow hits the ship or not based on the contour analysis, and entering S5 if the jet flow does not hit the ship; if the jet flow hits the ship, taking the position of the ship as a hitting coordinate, and entering S7; S5, calculating the deviation of the water cannon shooting by combining the coordinate position of the target ship and the position of the actual jet striking point; S6, converting the position of the actual jet striking point and the calculated deviation into a striking coordinate of the water cannon through a coordinate conversion method; and S7, feeding the striking coordinate back to a water cannon controller so as to correct the control parameters of the water cannon.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for evaluating the strike effect of a target ship based on jet edge analysis and strike deviation feedback. Background technique [0002] With the development of the globalization of the world economy, more and more ships travel to and from the world's major routes. Arbitrary berthing on the waterway hinders traffic, foreign national ships cross the border, and pirates rob merchant ships, etc., which interfere with the normal development of the world's shipping industry. The usual way to solve the above problems is to use water cannons to expel them. However, these law enforcement water cannons need to manually observe whether there is a jet strike, adjust the orientation of the water cannon aperture, and observe whether it hits the pirate ship. The work is cumbersome and intensive. Contents of the invention [0003] The purpose of the present invention is to solve the ...
