基于空白区域骨架线网眼的建筑物邻近度探测方法
A Building Proximity Detection Method with Skeleton Line Mesh of Blank Region
摘要
Abstract
Proximity relationship detection is an important technology for spatial clustering,pattern recognition,spatial analysis and data mining.Due to the multidimensional characteristics of the polygon and the complexity of the connection between the building and the surrounding spatial elements,there is a large uncertainty on how to scientifically describe the proximity of two buildings.Combined with the skeleton line mesh of blank region,a building proximity calculation method with the Gestalt principle was proposed.Firstly,the skeleton line mesh was constructed for the blank region between buildings.Then the distance,direction difference and offset of proximate buildings were calculated through the mesh.Finally,the proximity index describing the building proximity relation-ship was obtained by using the proximity direction difference and the visibility length ratio indexes as the weights to correct the distance.The experiment shows that this proximity index can effectively adapt to complex building groups and scientifically express the proximity relationship of buildings,and the spatial clustering based on it can also reflect the distribution pattern of building groups.关键词
