Many tools can be used for georeferencing point clouds: GRASS GIS, PC-AffineTrans, Java Graticule 3D, VisualSFM and so on. In practices, GRASS GIS

cannot handle large datasets; PC-AffineTrans only support a few data formats. More importantly, the georeferenced point clouds are warped (Figure 72). And all these programs aren’t able to georeference mesh models. CloudCompare has point-based aligned function which can be used for georefereneing mesh models directly.
