摘　　要：航碍区的提取是舰船航线分析与自动生成的基础。文中提出了一种基于海图水深的碍航区自动提取方法。该方法通过水深三角网的约束构建,安全等深线的自动追踪和碍航区的分析,实现了碍航区自动生成和表达。实验证明,所提方法可以根据安全水深变化,自动提取适应于不同舰船的碍航区。Acquisition of the obstacle areas is a foundation of the route analysis and automatic creation. A method for acquiring the obstacle areas automatically based on the water depth in a chart is proposed. Through constructing triangulated irregular net with constraints, tracing the safety contours automatically and analysis of the obstacle areas, the automatic creating and representing of the obstacle areas have been implemented. The experimental results demonstrate that the proposed method could acquire the obstacle areas suitable for various ships according to difference of safety depth.
