Control Points going into wrong positions
Answered
Hi, we are trying to scale our model so we've started to add some more CP's to the images however the controls aren't aligning into the positions we have placed them in the images. Is there a reason why this is happening?

Ok, I did an experiment that shows that in my case RealityCapture was not doing anything wrong.
Control point 21 had 4 images, but only two were from the current component. I took those two images and registered them together, and then the point showed up in the right place.
So I guess what was happening was that the other images that were used in aligning the cave wall "pulled" the wall inwards. The wall didn't line up with the control points because the wall was calculated based on more images than the point.
Dariusz might have a different problem though. -
I've had this a few times but narrowed it down to:
[list=][*]Too few images with CP in current chunk
[*]Misaligned image CP
[*]Distortion parameters not optimal (CP near edge of image)[/list]
The latter was mostly with fisheye images where the very outer edges of the image should be avoided for CPs but may be possible with "normal" lenses. Checking the tie points on the images with the CP may provide some clues if there are alignment issues throwing off CP locations
