Abstract

Abstract Ship anomaly detection is a vital aspect for monitoring navigational safety in specific water areas. Considering the effect of water channel boundaries, we propose the detection of an abnormal ship trajectory based on the complex polygon (DATCP) method to detect ship anomalies in this study. With the automatic identification systems (AIS) data from the Yangtze River estuary, a case study is created to verify the effectiveness of the proposed DATCP method. The case study results reveal that the proposed DATCP method can provide higher detection accuracy than the conventional A* algorithm. The feature analysis results indicate that ship anomalies are significantly influenced by ship type, time period, weather conditions and ship traffic characteristics.

基于复杂多边形的船舶轨迹异常检测

摘要船舶异常检测是监测特定水域航行安全的一个重要方面。在本研究中，考虑到水道边界的影响，我们提出了基于复杂多边形（DATCP）方法的异常船舶轨迹检测方法来检测船舶异常。利用长江口自动识别系统（AIS）的数据，建立了一个案例研究来验证所提出的DATCP方法的有效性。实例研究结果表明，与传统的A*算法相比，所提出的DATCP方法可以提供更高的检测精度。特征分析结果表明，船舶异常受船型、时间段、天气条件和船舶交通特性的显著影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
