by a statistical outlier removal approach [35]. For each point ρ in raw 3D point cloud, the average distance from ρ to its k-neighbor points was computed (di is the distance from the point ρ to the i-th neighbor...). In this research, noise removal was semi-automatic done by using an open-source software CloudCompare V2.10 [36]. Figure 1 Workflow for road surface extraction from MLS point cloud data After eliminating the noise......

, with repeated fluctuations. The fluctuations may be caused by the repeated entrapment and removal of the wear debris during the sliding process. Visual observation showed that the magnetron-sputtered Al... s. Furthermore, the curve of coefficient of friction is smoother than that at 10 N, which may indicate the easy removal of wear debris. Figure 7(d) shows the wear scar profiles after the dry......
