【摘要】：针对当前海图制图综合中航标手工选取作业效率低、选取结果受限于作业人员业务水平和工作态度等不足,提出了一种基于空间影响域覆盖最大的航标自动选取方法。通过定义空间影响域,创建空间影响域模型,加权评估航标地理位置重要性,设计空间影响域覆盖最大的分轮次自动选取策略,实现了航标的自动选取。实验结果表明:本文方法实现了航标的自动选取且结果符合《中国航海图编绘规范》要求,能避免手工选取可能存在的明显失误和不同作业人员可能导致的结果不一致性,作业效率明显高于当前普遍使用的手工选取方法。
[Abstract]:In view of the low efficiency of navigation mark manual selection in current chart cartography generalization and the limitation of selection result due to the operational level and working attitude, a method for automatic selection of navigation aids based on the maximum coverage of spatial impact domain is proposed.By defining the spatial influence domain, creating the spatial influence domain model, evaluating the importance of the navigation mark's geographical position weighted, and designing the automatic selection strategy of the spatial influence domain covering the largest number of times, the automatic selection of the navigation mark is realized.The experimental results show that the method has realized the automatic selection of navigation aids and the results meet the requirements of the Chinese nautical Chart compilation Code, and can avoid the obvious errors that may exist in manual selection and the inconsistency of the results that may be caused by different operators.The work efficiency is obviously higher than the manual selection method which is widely used at present.
