摘要
目前已有的结构面提取方法,有多点拟合、点云深度图像聚类、TIN格网的区域生长等方法。现有的提取方法对层面出露条件为平面形态的结构面有效,而对于出露条件为迹线形态的结构面无效。该文在现有算法基础上,分别对出露条件为平面和出露条件为迹线形态的结构面在三维点云空间中识别和提取方法进行研究。通过实例分析,验证了本文算法对平面状结构面和迹线状结构面提取的准确性和实用性。
At present,the extraction methods of structural plane include multi-points fitting method,point cloud depth images clustering,region growthing method of TIN grid and so on. The existing extraction methods are effective to the exposed condition as plane shape structural plane,and they are ineffective to the exposed condition as trace form structural plane. In this paper,based on the existing algorithms,the distinguishing and extracting methods of the structural plane as plane shape and trace form in three-dimensional point cloud space are researched respectively. Through the case analysis,it verifies the algorithm in this paper is accurate and practical to extract the plane shape structural plane and trace form structural plane.
