Because in the semantic reconstruction stage，our method is grid-based，it is understandable that the final reconstruction accuracy is related to the size of grid cell.Besides，to obtain an acceptable classification result，the cell size should be compatible with the point cloud density.That is to say，the point cloud density affects the final semantic reconstruction accuracy，as shown in Fig.15（the path inside the red ellipse of （a）is reconstructed in（c）but not in（b）） .
