Ship’s critical part detection algorithm based on anchor-free in optical remote sensing (2024)


What are the methods of ship detection? ›

Ship Detection
  • COSMO-SkyMed.
  • Ocean Wave.
  • Spatial Resolution.
  • Collision Avoidance.
  • Superhigh Frequency.
  • Radarsat.
  • Ocean Dynamics.
  • Histogram.

Why is ship detection important? ›

Ship detection has important applications in areas such as fisheries management, maritime patrol, and maritime rescue. It contributes to ship traffic management and the maintenance of maritime safety.

What is the best device for detecting the presence of a vessel? ›

Radar is a classic means for ship detection. It is most commonly exploited for navigation using rotating antennas on board of ships, and for vessel traffic control using antennas on the coast.

Which method is commonly used for ship identification? ›

To effectively detect ships, visual saliency detection can be used to find saliency regions according to global information instead of relying on local information. To prevent interference caused by local noise to a certain extent, the bottom-up visual saliency detection method based on data is commonly used.

How are ships monitored? ›

Radar: Vessel detection and tracking are based on radio waves. They emit a signal that bounces off a ship's metal surface and returns to the radar receiver, providing information about the vessel's location, distance, and direction. GPS (Global Positioning System): it is often integrated into vessel tracking systems.

What does the ship security alert system do? ›

The Ship Security Alert System (SSAS) enables a threatened ship's crew to silently request onshore assistance by using a hidden button to transmit an alert.

What are three important target data which can be received from radar tracking of other ships? ›

Indicate three important target data which can be received from radar tracking of other ships? Range, brilliance and gain buttons adjustment. Own course, speed and position. Course, speed and risk of collision.

How do ships detect other ships? ›

Marine radars are X band or S band radars on ships, used to detect other ships and land obstacles, to provide bearing and distance for collision avoidance and navigation at sea.

What is the most commonly used methods to determine ship's position? ›

The most commonly used method to determine position is then the classic terrestrial method based on bearings to landmarks (identified characteristic points) with known coordinates. Bearings are determined based on the recorded image of landmarks.

What are the three types of ship alarms? ›

In conclusion, the three types of ship alarms – the general emergency alarm, fire alarm, and navigation equipment failure alarm – play a critical role in ensuring the safety of vessels and their crew members.

What are the methods of locating shipwrecks? ›

Visual searches can be done from an airplane, by looking over the side of a boat, or by divers (using scuba equipment and snorkels) swimming or being towed across an area by a boat. If the search area is large, in deep water, or in water with low visibility, electronic equipment can help locate shipwrecks.
