What is the procedure for importing a Component?
Playing around I found if I selected the Component I wanted to export then selected Registration, it exported the Component. I could then import that Component into another project.
Hi Bill
Yes as you write can easily transfer alignment from project to project.
imagine as you align together 1 room and export it. and doing for say all few rooms and then put together. Its clean workflow and powerfull for any sort of datasets.
This is actually a very cool and powerfull tool. Hope to have some tutorial showing this soon.
There are more scenarios where this tool can show its real power:
Reconstruct piece-wise or working in parallel. Reconstruct a room/level/interior/exterior separately in parallel on more computers. Check every scene separately, if it contains all you want, use inspection tool to see connections between images, verify quality, etc. Then export these independent components and import them all into a new project. Click align and get a single complete scene. It will recycle all previous computations so it will be pretty fast.
Corrections - do you have some bad cameras/ghosts in a bigger scene? Simply reconstruct the bad place separately and import to the big scene. It will correct the scene locally.
You can also restrict export to some part of a component - simply select cameras which you want to have in your component and click export registration.
Hi thomasb,
thank you, that was really helpful!
I do have some issues with ghosts (am I correct in asuming it means areas with doubled surfaces?). How exactly do you do that? Just import the corrected local set into the old one and nothing else? Or do I have to align again? Because then it would just run another alignment over all, right?
I tried to correct these ghosts with control points but your solution seems so much faster!
Wishgranter,
I did not quite understand the workflow with several rooms.
How would there be an advantage to one big project? Just in terms of easier handling?
As I understood it would need another alignment to orient the rooms, which could result in a completely different result (in some details - e.g. ghosts). Gathering from the differing results of identical datasets, there must be quite some randomisation going on in the background (that ist no criticism!).
Anyone anything to say to these questions? 
Ok, in addition to my two previous questions:
I just did the workflow that thomasb suggested.
I opened a new project with the mal-aligned images and a few more correct ones of the area.
I aligned them (took 40000/80000 to work) and then exported the registration.
This I imported as a component into the big project but nothing changed.
Am I missing something?
Do I have to rerun alignment?
Which would loop back to one of my original questions:
Wouldn’t that result in a competely new alignment?
Or is the new one based on the previous alignments?
Help!
How can i align imported components?
They are only showing up under the “Scene”-tab as different components with different orientations and scales. :?:
Imported components are “star” marked on 1Ds toolbar side. To connect/align them, just press align. If there is a common visual information in images, or you have control points, or you have GPS/common coordinate system and enabled merging using GPS then it will create a single component.
You can also add a new set of images into the project and simply press align.
How exactly do you do that? Just import the corrected local set into the old one and nothing else? Or do I have to align again? Because then it would just run another alignment over all, right?
Exactly. Create a new locally corrected component and import back to the project. You need to press align again. It will reuse all previous information so it will be fast. Even if you add a new set of images it will recycle previous computations and it will not start over from scratch.
Thanks thomasb, that was very valuable info! 
“Align Images” or which align?
Hi Akiro
just use ALIGN…
If it not want to align get more images to cover the overlap or use ControlPoints like in this video

Hi Akiro,
as far as I know there is only one ALIGN, just in several different ribbons.
Was a bit confused at first, too… :mrgreen:
Ok, thanks! I thought i missed something. I tried the “Align Image” button, but nothing changed after the short processing time.
Is there a difference between “internal” components and exported/imported components?
I have to say that the interface is very confusing…
Yes and no.
The whole affair is just very complex and I find considering that the guys have done a pretty good job.
Took me longer to work out how Photoscan works, but then that was my first time in that area…
Hi Akiro
Yes it can be confusing on first try but when start to work with it will see the workflows are set very carefully and tested already by our customers over 1,5+ year. So if they would see its not ideal we would to change it. And teh customers work with BIG data. can imagine a daily work with 30-50k+ imgs datasets ? if there would be something not good, we would change it without problem.
Where its confusing for you ? in what part of the COMPONENT workflow ??
So for now just try process you data, try get real experience and you will see get it in hands in few days…
It’s getting better
e.g. one thing that i find confusing is the mutiple “Align Images” buttons on different tabs.
And the separation of the “View” selection (Scene) and the “Set Reconstruction Region” (Reconstruction).
Is there a way to display preview images of the images listed in the components? I find it very hard to select some images to place control points.
Hi Akiro
e.g. one thing that i find confusing is the mutiple “Align Images” buttons on different tabs.
their are on 2 ribbons
in workflow with all most used tool together and in ALIGNMENT ribbon 
same function…

when click to components can select the cams use the “color” 2D windows and set it like im do it in this video
https://www.youtube.com/watch?v=d8naLEtLqDY so have one img in window with CPs already placed
and change secondary 2D window to the img what need assign CPs…
Pardon the ignorance but I am a first time photogram user and still feeling my way around this.
I am trying to create a model of an object by combining the bottom to the other views. manage to create two good models but things go wrong when I try to merge.
tried using control points but comes up with huge 400+ pixels every time. Also not having luck importing component.
Just overlays the one model on top of the other.
Step by step instructions would really be appreciated.
PS I have tried just about all the other software and this is in a class of its own - just hope I can afford it.
Congratulations on a brilliant execution.
Hi Hennie van der Merwe
Can post some screens with the scene you trying to create ? so we can get better look on what need to solve…
Here are the two models that I am trying to merge
