Dear Sirs!
I have a some problem - in aligning process some cameras not aligning (dont have a gray arrow and dont include in field with model), especially angle cameras - top and lower. In Draft mode result is better, but some cameras not aligning too. As example left low angle camera is align and the same camera from right side - not align. Focus is exact and settings are identical. It sad to lost some cameras. Can some help me with align setting for this case?
Thanks

You likely need more photos inbetween or you need to define a few control points.

you can also change the alignment setting from Images overlap: high to medium or low.

That will widen the “search area” in the photos and possibly provide better alignment results.

It always helps to post a screenshot of the tie point cloud with cameras, too…

It seems the not aligning images are the ones where there is only litte of the object or background visible.
Therefore, RC has little to go on and I am not surprised.
What you can try is add ONE Control Point per image that does not align.
Sometimes, that helps.
Or you try raising the max features per mpx to 20000.

Type “yellow triangle” into the search bar and you will find the answer - it’s nothing to worry about.

Would probably work with the green rectangle as well - you need to cover the basics yourself with the help and forum!
I think they give you the number of tie points with the selected camera…

There are different numbers recommended in the Help manual. 1 control point is almost never enough.

Well, it DOES work for me on a regular basis.
I guess it depends on the situation.
The advantage with only one point is that it will not screw up the image distortion, which happens easily with 3 or more points.
Plus it is a relatively good effort to effect ratio, which can get out of hand when placing more CPs. Very often in my experience it only moves the problem to a different area of the model and it is hard to find a point to stop.
With one point, it either works or not and if not you can still pull the plug or go back and take more images…
