Figure 2: Dataset Urban ♯1: (a) Example of 3D chunk containing N = 3 Mpts, acquired in Paris (France) over an approximative length of 82 m
Figure 4: Decimation results obtained for the dataset Urban ♯1: (a) full resolution smoothed mesh: N t = 2.54 Mpts; (b) zoom-in view in the area around the sidewalk border indicated by the white arrow from Figure (a); (c) wire-frame view of the decimated m
Figure 5: Surface reconstruction results for the dataset Urban ♯2 over 51 m length. (a) Google street view of the surveyed area (although not exactly the same pose, it is useful for surface inspection purposes), (b) N p = 1.01 Mpts, N t = 2.026 MTriangles,
