Always have the same scale from my scanning rig

Hi, I have a photogrammetry RIG and the cameras are always in the same place. By setting the appropriate scale using the ‘define distance’ tool, I would like to transfer this information to my next scans. I have tried all possible options, and I want to be able to do this in the Aligment/Update tab after reading the file that I will export. I need to get the same scale as the previous scan. Best step-by-step.

Great, thank you, but it works when we have markers all the time on scans. And how do I make it so that after making a scan with markers, making a ‘calibration’ of the cameras, on the next scan where I don’t have markers, RealityCapture knows what the camera data is and sets the same scale as for the scan with markers?

For the first calibration it is good to have markers (to get proper scale an orientation). Then you will export XMPs for the cameras from the rig and you can use the same XMPs for new images from the same camera rig (where is is not necessary to have the markers).

It works. Thanks a lot. I exported xmp at the wrong time.
