Discontinuity sets play an essential and pivotal role in the deformation monitoring and stability analysis of the rock mass. but there are still many challenges for accurately and rapidly extracting discontinuity. In this study. an extraction and characterization method of discontinuity sets based on point cloud supervoxel segmentation was proposed. https://www.nacrack.com/mega-pick-Legacy-Kelly-Green-Spear-Cool-Fit-Adjustable-Visor-White-quick-deal/
