AI Technical Summary

Technical Problem

The prior art is difficult to accurately detect the attitude of sea ships, especially in wide-frame space-based remote sensing images. Ship attitude information is crucial for track analysis and prediction, but is often affected by interference from clouds, islands and noise points.

Method used

By extracting semantic segmentation areas of ships and wakes based on global remote sensing images, the ship's attitude direction is determined. The specific steps include: obtaining the semantic segmentation areas of the ship and the trails, determining the center points of these areas, determining the initial attitude direction of the ship based on these center points, and further determining the attitude direction of the ship through the long and short axis directions of the semantic segmentation areas of the ship.

Benefits of technology

It realizes rapid and accurate detection of the attitude of maritime ships, reduces false alarms or missed inspections caused by interference, and improves detection accuracy.

Abstract

The present invention provides a ship attitude detection method, device, electronic device and storage medium, which relates to the field of visual detection technology. The method includes: based on a global remote sensing image containing a target ship, obtaining a ship semantic segmentation area corresponding to the target ship and a wake semantic segmentation area corresponding to the wake of the target ship; determining a first center of the ship semantic segmentation area and a second center of the wake semantic segmentation area; determining a first attitude direction of the target ship based on the first center and the second center; determining the major axis direction and the minor axis direction of the ship semantic segmentation area, and determining a second attitude direction of the target ship based on the major axis direction, the minor axis direction and the first attitude direction, and using the second attitude direction as the attitude detection result of the target ship. The present invention can effectively realize the rapid and accurate detection of the attitude of a ship at sea.
