摘要: 提出了一种基于动态水位的航线可行性分析方法,通过追踪安全等深线,求取随瞬时水位时变的障碍区,然后分段判断航线与障碍区的相交情况,测试航线的可行性,求解可行性时间。实验表明,该方法能有效地分析动态水位影响下的航线可行性,扩大通航能力,缩短航程。

Abstract: A method for analyzing a planned route considering the effect of changing water level is proposed.The method traces safety contour,and computes dynamically obstacle areas with instantaneous water level.The feasibility is tested by the intersection of the subsection in a route and time-varying obstacle areas,and navigable time window is computed.Experimental results demonstrate that the proposed method can conclude effectively feasibility of the route considering instantaneous water level，moreover it can lead to greater available depths in a route and a shorter distance for safe navigation.
