Unreferenced terrestrial 3D laser scan with WGS84 aerial images

[densecloud]

Hi !
I've an unreferenced 3D building facades scan (no Local X,Y) along with aerial images WGS84. To "match" both I've tried the following :

• clear images coordinates from reference pane, align, define markers on images and pin markers on the LAS cloud (and attempting vice versa)
• align images, create markers set 1 from sparse cloud, create markers set 2 on same LAS locations and assign set 1 WGS84 coordinates to set 2, LAS cloud referential set to WGS84

I can't build mesh from terrestrial 3D scan since the whole building has not been scanned (3 facades only)
I cant' either align and merge both dense clouds...

IMHO there's nothing I can do, am I right ?
