摘    要:本文在介绍了已有的“基于Circle特征变换的点群选取算法”(测绘科学2005年第3期)基础上,提出了一种改进算法。详细分析了已有算法在线化简过程中对聚类的过度依赖性和线化简过程中的逻辑不一致性等两个主要不足,对特征空间中的线化简等关键步骤进行了改进。最后就改进算法的结果与原先算法的结果进行了对比分析与评价。

关 键 词:地图自动综合  选取  点群目标  Circle

Abstract:This paper introduces an improved method based on the existed algorithm named "A Model of Point Cluster Selection with Circle Characters"(published in Science of Surveying and Mapping,2005,3).Two lacks of old method,excessive dependence on cluster and logic disaccord during the process of simplifying line,are analyzed.The improved work is done to the key step such as simplifying line in characteristic space.Finally the results with improved algorithm and original algorithm are compared and assessed.
Keywords:map automatic generalization  selection  point cluster  circle
