不确定区域间方向关系的相似性度量方法
Similarity Assessment of Approximate Direction Relations
摘要
Abstract
Similarity of spatial relations is with wide applications in normal life .Research on similarity assessment of exact direction relations is more perfect ,but the presented methods based on crisp regions can not deal with the approximate direction rela-tions .Based on the extended direction relation matrix (EDRM ) ,the paper proposed a method for similarity assessment of approxi-mate direction relations ,and then the algorithm SA-EDRM was implemented ;on the basis of the variation of location and scale of the target object ,different scenarios were generated to test SA-EDRM ,and the experimental results verify the effectiveness of the al-gorithm .In the end ,an instance of Agricultural GIS was used to explain the practical value of this article .关键词
