摘　　要：以三维激光扫描雷达获取精确的室内点云数据为研究对象,提出了一种快速、准确的提取点云中的建模信息和各模型相互关系的方法,对室内三维场景进行重建。首先对室内场景进行多站三维激光扫描,对获得的三维激光点云数据进行预处理、配准得到整体的点云模型,然后进行截取取得截面图,对截面图进行重绘测量得到其精确数据,最后根据所得数据的特点使用不同的建模软件对室内的框架和细部结构分别重建并组合,完成室内建模工作。This paper presents a quickly and accurate method of extracting modeling information in point cloud and the interrelationship of each model to reconstruct indoor 3Dscene based on accurate indoor point cloud data which is acquired from 3Dlaser scanning radar.Firstly,multi-station 3Dlaser scanning is performed on the indoor scene,the acquired 3D laser point cloud data is preprocessed and the 3Dpoint cloud is completed.After the whole point cloud model is obtained,the cross-sectional view of the cross-section is obtained and the accurate data are obtained by redrawing the crosssection.Finally,the indoor model and the detailed structure are rebuilt and reconstructed according to the obtained data using different modeling software.
