Research on Earthwork Quantity Calculation Method Based on Cloth Simulation Filter and Point Cloud Poisson Surface Reconstruction Technology
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.
