General / Align drone photogrammetry with a terrestrial scanner point cloud
« on: October 15, 2021, 05:50:21 PM »
Hello, I've been widely searching for this subject but found not a proper solution, so I'm starting a new topic.
My purpose is to merge drone photogrammetry with terrestrial scanner point cloud, pretty much an actual theme. I'll list what I am trying to do:
I was expecting to simply pick common points and all come in place at once. Evidently I'm thinking wrong, because 'Align chunks' function is greyed and I can't execute it, probably because chunk #2 is not referenced.
The only thing about this argument I've found so far is this article from the helpdesk.
Isn't enough to have one chunk referenced for the alignment to happen?
I have a drone and a Leica RTC360, what is the procedure I should rely on, to merge everytime the work of both instruments in Metashape?
My purpose is to merge drone photogrammetry with terrestrial scanner point cloud, pretty much an actual theme. I'll list what I am trying to do:
- create 2 chunks, one for the photogrammetry data, and the other one for the scanner data
- in chunk #1 load all the drone photos and produce the dense cloud, referenced by GCPs in use
- in chunk #2 import the scanner point cloud, unreferenced (Local System), using a .E57 file published by Cyclone REGISTER 360
- align and merge chunks
