AI Technical Summary

Technical Problem

Existing technologies for identifying overloaded vessels at sea suffer from low accuracy and poor reliability, especially in dynamic environments where it is difficult to accurately identify vessel load, leading to regulatory blind spots and safety hazards.

Method used

The system employs an integrated air-space-ground system, which uses multimodal data acquisition and processing, including aircraft, space-based networks, and shore-based networks, combined with visible light cameras, lidar, millimeter-wave radar, and meteorological satellites, to perform multi-source data fusion, perform sea wave height compensation, ship attitude compensation, and ship speed compensation, dynamically calibrate water level to obtain the true draft, and combine machine learning and computer vision for identity recognition and overload determination.

Benefits of technology

It achieves high-precision and reliable identification of overloaded vessels at sea, reduces interference from dynamic environments, improves the accuracy and coverage of identification, and avoids the limitations of traditional regulatory methods.

Abstract

The present application provides a kind of offshore ship overload identification method, computer storage medium and system, it is related to the technical field of multi-modal data processing, by the preset space-time integration system acquisition multi-modal data, break through the single data source limitation, realize the all-around, multi-angle, real-time dynamic coverage to target ship, significantly improve data dimension and space-time resolution, avoid the recognition error caused by data missing or visual angle blind area, lay reliable data foundation for subsequent high-precision analysis.Based on multi-source fusion data, the identity of the target ship is identified, and the initial draft of the ship is further obtained based on this, to ensure that the subsequent compensation and overload criterion is customized for a specific ship, and sea wave height compensation, ship attitude compensation and ship speed compensation are introduced, which avoids dynamic interference in cooperation, and finally obtains the overload identification result of the ship based on the real draft, the ship navigation area and the navigation season, improves the accuracy and reliability of the offshore ship overload identification.
