基于原型模板形状匹配的建筑多边形化简

Building-polygon Simplification Based on Shape Matching of Prototype Template

在大比例地图综合中,建筑多边形的形状化简占有很大的比重,本文用形状数来描述建筑多边形的形状,通过形状数间的最小编辑距离在动态模板库中匹配相似的模板,用匹配成功的模板来置换原要素而实现建筑多边形的化简。实验证明,基于形状数的建筑物形状相似性匹配结果与人的视觉感知基本一致;基于形状匹配的建筑物化简方法具有很强的实用性。

We apply shape-number method to represent polygon shape and by least editing distance computes the shape similarity.The simplification of building polygon is conducted by replacing the original polygon with the matched template object.The method based on shape matching is an attempt of application spatial recognition in map generalization.The experimental results show that the matching similarity based on the shape-number calculating is consistent with human cognition able to be practically used in building generalization.
