Ship detection method and device

Abstract

The invention relates to a ship detection method and device. The method comprises the steps of obtaining an accurate positioning rotating rectangular frame of a ship in a remote sensing image based onship features of the remote sensing image; extracting a slice image of the ship in the remote sensing image based on the accurate positioning rotating rectangular frame of the ship in the remote sensing image; inputting a slice image of a ship in the remote sensing image into a pre-established classification model, and obtaining a ship model of the ship output by the pre-established classification model; according to the ship detection method provided by the invention, the classification difficulty is low, the positioning result is more accurate, adjacent ship targets can be distinguished, target confusion is avoided, the influence of insufficient training samples and non-uniform categories is reduced, the classification performance of the classifier is improved, and the identification ofspecific models of the ship targets is realized.

Description

technical field [0001] The invention relates to the technical field of image processing and computer vision, and in particular to a ship detection method and device. Background technique [0002] In remote sensing images, ship detection has always been a concern. In recent years, with the development of sensors, radar and other technologies, the resolution of remote sensing images has been rapidly improved, making ship detection play an increasingly important role in maritime security, port management, national defense construction and other fields. [0003] At present, the research of ship detection is mainly divided into two aspects: positioning problem and classification problem. The localization problem is to detect ship targets in high-resolution remote sensing images and represent them in the form of a horizontal rectangle or a rotated rectangle. Common methods include SVM-based methods, convolutional neural network-based methods, etc. Another is the classification ...
