Merging components with control points (SOLVED)

Hi, I have a dataset of 1086 images which generates lots and lots (about 40) of separate components (the images taken with not to good lightning which is the reason for the bad match I guess).
They are indoor images, so I have no GPS exif data.
I can’t get to the same physical place again so I can’t take any additional images.
I try to merge two components as per the manual: I choose two components that contian more or less the same images, each component containing about 10 images.
In each component, I’ve selected a number of images (about 6 each) in which I’ve added lots of control points (30+).
The vast majority of these control points is visible in each image.
After that, I click on “align images”.
The result after about 10 mins calculating: nothing.
The two components are still two separate components.
Anybody know what I am doing wrong?

Greetings,

Steven

Hello, Steven,
so you managed to get it all down to 2 components by adding some control points? Even if not, adding more control points could still do the trick in your case - you just need to find the right ones, which can be sometimes tricky. They should be distributed more in space, adding a lot of points on a plane will not help much.

Hi I figured it out: when you re-align the images, a whole new set of components are created, with an index added to them. So if you had:
Component 0
Component 1
Component 2
Component 3
Component 4

And you you managed to bring that back to two, that you component list will look like this:
Component 0
Component 1
Component 2
Component 3
Component 4
Component 0 (1)
Component 1 (1)

You’ll have to manually delete the “old” components.

Hi Steven,
Exactly, the app shows always all components - old and new. So you have do delete manually which components you do not like. We will make updates in UI to make it better distinguishable - which component belongs to which alignment round.

This is really not clear from the UI. I had no idea I had to clear my old components.

Well, you do not have to, it is just a recommendation to remove the components with very few images aligned.

@admin It’s been “2 years” now, is any progress being made? BTW, I’m a new user. It didn’t take me too long to discover that recalculated components were just being added to the list (instead of replacing the old calcs), but my lists were getting super long (and I was getting annoyed scrolling up & down between Control points and Components) before I discovered that you could get rid of the old components (but through a VERY painstaking process). I’m sure that both issues are a common sticking point for most new users, so it would be good to see an improved interface - maybe by grouping all components together into alignment runs, so at least you only need to click one “x” to delete?

Until then, IS there an easier way to get rid of all the old components? I doesn’t look like you can select multiple, so I have to hover and click on each “x” (and be careful to not select the component instead), but I’m wondering if there’s just a “trick” that I’m missing (I’m slowly discovering some of the functionality I’ve been wanting, such as selecting all images associated with a component, etc.).

It would be GREAT if it was possible to select many components by clicking the first, then holding SHIFT and clicking the last, and delete them all in ONE go.
