基于红黑树与K-D树的LiDAR数据组织管理
Data Organization and Management of LiDAR Based on Red-black Tree and K-D Tree
摘要
Abstract
LiDAR point cloud is a 3D point set composed of massive discrete laser dots which exist in both plane and vertical directions. Because of lacking space topological relations among the discrete dots of LiDAR point cloud, it is important to establish an appropriate data structure for LiDAR point cloud as the foundation of LiDAR process-ing. According to the structural characteristics of LiDAR point cloud data, a two-level data structure with "non-null" regular cube grid and K-D tree is established for the organization and management LiDAR point cloud using red-black tree and K-D tree to build. The structure could reduce the structural redundancy and improve indexing ef-ficiency.关键词
