Embodiment Construction

[0092] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work all belong to the protection scope of the present invention.

[0093] The embodiment of the present invention provides a ship classification method, referring to figure 1 , which can include:

[0094] S11. Determine the driving state of the vessel to be analyzed;

[0095] Among them, the driving state refers to the relative driving direction with the monitoring radar and which state it is in maneuvering, turbulent or stable driving. Among them, the relative driving direction includes three situations where the ves...

Abstract

The invention provides a method and device for classifying ships and electronic equipment. The method comprises the steps of determining a travelling state of one to-be-analyzed ship; when the travelling state is a one-way steady travelling state, calculating an altitude angle of the to-be-analyzed ship, obtaining a one-dimensional range image of the to-be-analyzed ship; selecting a target one-dimensional range image with the maximum similarity to the one-dimensional range image from a one-dimensional range image simulation database built in advance according to the altitude angle and the one-dimensional range image and taking the type of the ship with the target one-dimensional range image with the maximum similarity as the type of the to-be-analyzed ship. Through the method, classification of the ships can be achieved and the problem that a one-dimensional range image-based method is needed to determine the type of each ship in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of shape recognition, and more specifically, relates to a ship classification method, device and electronic equipment. Background technique [0002] Today, radar is often used to acquire one-dimensional range images of ship targets. Among them, ships include ships and merchant ships. The one-dimensional distance image is the vector sum of the projected scatter point echoes acquired by broadband radar signals on the radar line of sight, which shows the structural distribution and geometric shape of the ship target, and indicates the distribution of the ship target scatter points along the distance direction, which is the ship category Identification provides important information. [0003] When a ship is traveling at sea, in order to ensure safety at sea, the ship is often identified, such as judging whether it is a ship or a merchant ship, but how to determine the type of ship based on the one-dimensional ra...
