A text file with Ground Control Points (GCPs) must exist in the same folder where the point cloud is located, and the textfile must have the same name like the point cloud, but ending on .txt instead of .ply.
The text file with GCPs must have the following format with one GCP per line:
x y z east north height status
The georecitifictation method used is a 3D orthogonal rectification where angles are preserved. 3D objects are shifted, scaled and rotated, but no shear is introduced. Please read the output of the module, in particular the root mean square (RMS) errors.
v.ply.rectify optionally exports the georeferenced point cloud not only with real coordinates, but also with shifted coordinates (-s flag) for display in meshlab or similar software that can not deal with real coordinates. The exported PLY point clouds will be in the same folder like the input PLY point cloud.
v.ply.rectify -s input=pointcloud.ply
Available at: v.ply.rectify source code (history)
