居民地要素化简的形状识别与模板匹配方法

针对居民地要素的分布和表达具有典型模板化特点,本文通过对其形状结构和区域环境进行分析,运用形态抽象概括和区域环境典型化基本原则构建一批模板作为居民地目标化简与典型化表达的候选形状,并基于转角函数的形状描述算子,计算居民地目标与模板之间的相似性程度。该方法从形状认知的角度出发,通过寻找与目标形状结构特征相似的模板替换原目标来完成化简操作,能较好地保持居民地目标的整体形状结构特征,同时兼顾了综合前后的面积均衡。通过真实数据进行试验,结果表明该方法具有较强的可靠性和实用性,可规模化应用于地形图上的地图综合实践。...

Aiming at the typical template characteristics of building representation,this study built a series of templates to abstract the building shape by generalizing building polygons and analyzing the typical characteristics of regional environment.The shape description operator used the turn function method through the measure of the similarity between the building target and the template.From the perspective of shape cognition,this method conducted the building simplification by searching and matching the most similar template to replace the target building,The presented method is able to guarantee the overall shape structure unchanging and maintaining the area balance after the simplification.The experiments under real data show that the method holds high reliability and practicability,able to be widely applied to practical map generalization.
