Measuring method of building basement based onthree-dimensional laser scanning technology

现行建筑物地下室测量方法在实际应用中效果不佳,其测量值与实际值相差较大。针对现行方法存在的不足与缺陷,提出基于三维激光扫描技术的建筑物地下室测量方法。通过对建筑物地下室进行三维激光扫描,获取地下室空间点云数据,采用统计滤波算法处理地下室点云数据滤波,利用两站配准方法处理地下室点云数据,建立建筑物地下室三维空间模型,实现基于三维激光扫描技术的建筑物地下室测量。试验表明:该设计方法皮尔逊相关系数大于0.9,能够实现对建筑物地下室的精准测量。本文成果可为地下室测量效率和精度的提升提供一定的借鉴与参考。

The current measuring method of building basement is not effective in practical application,and its measured value is quite different from the actual value.In view of the shortcomings and defects,a measuring method for building basement based on 3D laser scanning technology is proposed.Through the three-dimensional laser scanning of the basement of the building,the basement space point cloud data is obtained,the statistical filtering algorithm is used to process the basement point cloud data filtering,the two-station registration method is used to process the basement point cloud data,the three-dimensional space model of the building basement is established,and the measurement of the building basement based on the three-dimensional laser scanning technology is realized.The test proves that the Pearson correlation coefficient of the design method is greater than 0.9,which can achieve accurate measurement of the basement of the building.The results can provide a certain reference for improvement in the efficiency and accuracy of basement measurements.
