基于机载LIDAR建筑类数据提取算法综述
摘要:机载激光雷达测量可以快速获取高精度的城市三维信息,用于三维城市建模。建筑是城市的主体,从机载激光雷达数据提取建筑类数据一直是学者研究的热点。提取建筑类数据主要步骤包括:数据预处理、建筑检测、屋顶重建、边界提取、建立模型和规则化。本文简要综述这几个方面的研究进展和从机载激光雷达数据提取建筑类数据的难点及发展方向。
Abstract:Airborne laser radar measurement can quickly obtain the 3D information of high accuracy,which can be used in 3D city modeling.Construction is the main body of the city,and it has been a hot research topic in the construction of data extraction from airborne LIDAR data.Data extraction from airborne LIDAR data mainly includes the following steps:data preprocessing,building detection,roof reconstruction,boundary extraction,establishment of model and rule.In this paper,the research progress of this field is summarized,and the difficulties and developing direction of data extraction from airborne LIDAR data are described.
