摘要
提出了一种基于布料模拟滤波和点云泊松曲面重建技术的土方量计算方法,该方法首先通过靶标将多站数据进行配准,获得测区的整体点云数据,然后采用布料模拟滤波算法(Cloth Simulation Filter, CSF)剔除植被等非地面点,获取地面点云,第三,采用泊松曲面重建的方法对地面点云进行三维重建,依据设计要求,通过设置格网宽度得到三维模型的体积,从而实现区域土方量计算。最后,通过选择多阶次拟合来分析格网尺寸对土方量计算精度的影响。
In this paper,We propose a earthwork quantity calculation method based on cloth simulation filtering and point cloud Poisson surface reconstruction technology.Firstly,we register the multi-station data through the target to obtain the overall point cloud data of the measurement area;And then we adopt the cloth simulation filter algorithm(Cloth Simulation Filter.CSF)to remove non-ground points such as vegetation to obtain the ground point clouds;Thirdly,the Poisson surface reconstruction method is used to reconstruct the ground point cloud,according to the design requirements,we set different grid size to calculate the volume of the three-dimensional model,so as to realize the calculation of regional earthwork quantities.Finally,we analyze the influence of grid size on the accuracy of earthwork quantity calculation by selecting a multi-order fit.
