Abstract

The invention relates to the field of artificial intelligence, in particular to a ship detection method, device, electronic equipment and storage medium under the influence of ocean waves. Including steps: obtaining the image to be recognized; extracting the features of the ship in the image to be recognized, outputting a target frame containing the image of the ship; intercepting the image information of the image to be recognized in the target frame, and obtaining the pixel of each pixel in the target frame value; the pixel points in the target frame whose pixel values ​​are in the white range are merged to obtain the area of ​​white pixels; the area boundary of white pixels is ruled to determine whether the area boundary is the boundary of the wave area; when the area boundary is When the boundary of the wave area is used, the target frame containing the image of the ship is corrected by using the wave area to determine the actual position area of ​​the ship. The target frame containing the ship image is corrected by using the wave area, and the actual position of the ship in the image is further determined, thereby improving the accuracy of ship position detection.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a ship detection method, device, electronic equipment and storage medium under the influence of ocean waves. Background technique [0002] As a part of object detection, ship detection has always been a hot topic in the field of computer vision and pattern recognition. In many applications such as marine security, maritime monitoring and management, ship detection can provide decision-making information for it. [0003] Traditional target detection is usually based on machine learning. Through manual feature design and feature extraction, the extracted features are input into a certain classifier to achieve the target detection task. With the development of deep learning, object detection has entered a new stage. Different from the traditional manual design of features, convolutional neural network (CNN) can automatically extract more representative features. Since there ...
