摘要
采用栅格划分和法向量估计的点云数据压缩法,对海量的云数据进行压缩处理,并通过线路架构模型重建,得到准确的实物数字模型,进行横断面的截取及空间距离计算。
Through applying grid division and point cloud data compression method of the normal estimation,the paper carries out data compression for the numerous cloud data,re-establishes circuit framework,and obtains accurate material digital model,and finally carries out the crosssection interception and spatial distance calculation.
