摘要
区域分析法是在作战测绘保障中研究战场环境的基本方法。特定区域的准确、详细的描述 ,需要获取区域矢量边界和建立区域之间的拓扑关系。以往通常采用等值线追踪算法获取描述区域的矢量边界 ,其结果在边界的自封闭性、完整性和建立拓扑等方面存在问题。文中就如何对规则格网数据所描述的区域通过二值化处理 ,运用八向邻域的有向判断策略 ,提出了一种获取描述区域矢量边界的算法。
The method of region analysis is the fundamental way in the study of battlefield environment.The accurate description of specified region needs the acquisition of its boundary and the foundation topographic relation between regions .This paper gives an algorithm of the acquisition of boundary vector of regions through a way of bi value processing and the directory judgement of the neighbouring domains in eight directions.
