最近，航海技术发展迅速，在贸易、军事、科研等众多领域起到越来越重要的作用。人们对于舰船航行的规划、仿真、监控与跟踪等方面的研究更细致、更全面。本文主要研究基于舰船航行中跟踪到的稀疏航迹点的航线估计问题，用于态势图的仿真显示。为了估计出通过所有航迹点、合理、平滑的航线，我们提出了由粗到细的航线估计算法，该算法主要包含三个层级。提出的算法使用数据量较小的经验航海线路图和全球海陆分布图，这两种图的数据获取容易，并且可实现较快速的航线估计。大量实验证明，提出的由粗到细的层级算法能较好的完成航线的估计。同时，提出的算法也可以用于舰船航行前的航线规划。算法仍然存在一些问题和不足，例如没有考虑海洋水深等问题，这将是我们下一步的研究内容。

Recently, the navigation technology achieves fast development and is playing an increasingly important role in areas of trading, military, and scientific research. About the route planning, simulation, monitoring and tracking of ship, more detailed and more comprehensive researches are being done. This paper focuses on the shipping route estimation based on discrete track dots, which is used for shipping route display in the situation map. To estimate a possible and smooth route going through all track dots, we propose a coarse-to-fine method, mainly including three levels. This method uses the experience nautical chart and the global sea and land distribution map, which are easy to get and help to achieve fast route simulation. Extensive experimental results show that the proposed coarse-to-fine shipping route estimation algorithm can fulfill the route simulation task. Meanwhile, the proposed method also can be used for shipping route planning before sailing. However, there are some problems about the proposed algorithm, such as without considering the water-depth condition which may influence the shipping route, but the research will continue.
