Abstract

The invention discloses a ship retrieval method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a to-be-retrieved image, and determining whether a ship exists in the to-be-retrieved image or not; when determining that there is a ship in the to-be-retrieved image, cutting a ship image of a target size from the to-be-retrieved image; performing feature extraction on the ship image of the target size to obtain a target ship feature map; and retrieving a target ship picture matching the target ship feature map from a preset ship feature library. According to the ship retrieval method, the ship retrieval difficulty is reduced.

Description

technical field

[0001] The invention relates to the field of image processing, in particular to a ship retrieval method, device, computer equipment and storage medium. Background technique

[0002] As an important target of sensing information in coastal areas, the movement of ships is an important content of ship detection in the field of remote sensing images. Because satellite images of coastal areas contain many different scenes, including building areas, vegetation areas, mountains, rivers, etc., ships occupy a small proportion of them. As a small ground object, ships have relatively little feature information, and it is difficult to retrieve ships. Contents of the invention

[0003] Embodiments of the present invention provide a ship retrieval method, device, computer equipment, and storage medium to reduce the difficulty of ship retrieval.

[0004] The present invention proposes a ship retrieval method, comprising:

[0005] Obtain the image to be retrieved, and d...
