Combine two registrations

[ponsrud]

Hi, I have scanned a buidling, and I am creating a new registration for each floor using visual aligment.
Now I have created a registration for each floor and I want to combine the registrations with each other using visual aligment in overlapping areas.

I was thinking that the "import registration" tool would to the trick, but when I use that function it only imports the registrations as ungrouped scans, and it will only align one scan at the time. So, my question is: is there a way two combine two registraions using visual aligment?

Heyo,

I watched a webinar from Leica that covered a similar topic, merging registrations from internal and external scanning of a building. I believe the process they used might work in your situation. Assuming you have a separate registration for each floor, the instructions below might help.

Try this:
1. Unify the point cloud for each floor separately.
2. create an empty scanworld (not modelspace) for each floor, naming them appropriately (by floor)
3. copy the unified point cloud into the Control Space of each new scanworld for the separate floors
4. you should now be able to create a new registration, importing these new scanworlds (containing the unified point clouds, separated by floor)
5. if you do a visual alignment between 2 floors/scanworlds, it will show the 2 unified floors in the Blue/Orange.
5. visually align each floor to each other, assuming your using stairwells.
6. Once your happy, freeze the new registration, which should now have each floor aligned to the one above/below it.

I would test 2 adjacent floors before running the whole thing.

All the best,
Scott

Even though they are ungrouped they still have the connections.

Go to your notes and create a visual alginment between the overlapping scans on each floor to join them together, optimize constraints, register then create the model space and it will all be together!

I still find the time to put them all in the one group so it looks neat!

Thanks both of you for your replies

I tried steves01x method, and as he said, it seems like the connections are still there eventhough they are ungrouped. So I just imported all my registrations in one new registration, used visual aligment in overlapping areas, registered and it was all good!

Thanks again!

Hi, can you explain in detail how you did this. When I create a new registration and try to bring in the already aligned registered files it doesn't work.

Our workflow is to have some of the same scans from each registration/floor in both floor registrations. So if floor one has scans 1-100 then the second floor registration will contain scans 98-200.

After you register the 1st floor and the second floor separately you can now create a new registration and choose file import registration and select the 1st and 2nd floor registrations. And because you had common scanworlds in both registrations they will be automatically registered as the links are brought forward.

You don't say which software you are using Cyclone Core or Reg 360. But in Reg 360 you can have a floor in each site map and then drag one floor registered bundle into another site map with a different floor registered bundle and link the two bundles, without any overlapping scans. Just have a scan with overlapping areas -for cloud to cloud registration, between the two floors.

Which software are you using?

Hello .

Do you remember what leica's webinar have you seen ?
It's always online ?

Thanks for your answer.
