摘要 分析了国外点云数据处理中数据缩减方法的研究现状,针对实际工程中三维激光扫描数据采集的过密情况,提出利用扫描间隔进行点云数据直接缩减的方法,并编程实现所提出的算法。通过对真实的三维激光扫描点云数据的缩减处理,建立点云数据直接缩减的预测模型。 The foreign research background of point cloud data reduction is reviewed in the paper. To the dense data processing of point cloud, the direct reduction method of point cloud is proposed and the provided algorithm is programmed. Finally, the forecasting model of data reduction is build by the reduction processing with real 3D lair scanning point cloud data.
