Calculation on ship-bridge collision risk of Kunzi model based on ship domain

2021 IEEE 5th Information Technology,Networking,Electronic and Automation Control Conference (ITNEC), 2021
With the construction of inland river bridges, the frequency of ship-bridge collision accidents has gradually increased. However, there are few algorithms for risk identification of ships and bridges. The reason is that there are many types of bridges and ships, which leads to the lack of universality of the algorithms.

ADCG: A Cross-Modality Domain Transfer Learning Method for Synthetic Aperture Radar in Ship Automatic Target Recognition

IEEE Transactions on Geoscience and Remote Sensing, 2023
Due to the powerful feature extraction and expression ability of convolutional neural networks (CNNs), exceptional success has been achieved in the field of ship automatic target recognition (ATR) of synthetic aperture radar (SAR).

A novel dynamic quaternion ship domain

Fifth International Conference on Intelligent Control and Information Processing, 2014
Based on ship maneuverability and human reliability models, a novel dynamic quaternion ship domain (DQSD) model is firstly proposed by effectively combining subsystems of ship dynamics, human performance and navigation environment, which results in the quantitative and analytical study on ship domain models.

A Risk Assessment Algorithm for Ship Domains

2018 37th Chinese Control Conference (CCC), 2018
A risk assessment algorithm for ship domains is proposed in this paper. Two different cases are considered to assess the risk of own ship and target ship. In the case that the ship domains are separated, the maximum margin is used to measure the risk.

A Revisit of the Definition of the Ship Domain based on AIS Analysis

Journal of navigation, 2018
When ships approach each other, they should keep a minimum area around them clear of other vessels in order to remain safe. The geometrical shape of this area has been studied since the early 1970s and is defined as the ship domain.

Semi-dynamic ship domain in the encounter situation of two vessels

Developments in the Collision and Grounding of Ships and Offshore Structures, 2019
: There exist numerous examples of ship domains that are rooted in the concept of Fujii and Goodwin. Initially, the idea was developed to evaluate the capacity of waterways by calculating the probability of accidents in the fairways.

A Domain-Adaptive Few-Shot SAR Ship Detection Algorithm Driven by the Latent Similarity Between Optical and SAR Images

IEEE Transactions on Geoscience and Remote Sensing
Detecting ships in synthetic aperture radar (SAR) images poses a formidable challenge, primarily attributed to limited observation samples and complex environments.
