Hi
I have the following problem:
On day 1 I calibrated 5 cameras (multi view calibration) in some reference frame that I constructed with markers. Then, I take images of some scene.

On day 2, I realized that 3 from 5 cameras had moved and 2 camera stayed fixed. The scene also changed. So I put back the markers and re-calibrate all cameras with respect to a bit different reference frame (different to day 1).

I want to project the calibration of day 2 to the reference frame of day 1.
I assume that if I know the locations and the orientations of the 2 fixed cameras in the reference frame of day 1, I can use them to find the other 3 cameras in the same reference frame.

So I put the locations and orientations of the 2 fixed cameras in the Reference panel, but it doesn't update the other 3 camera locations (in the estimated Reference panel). As for the orientations, it does update for the other 3 cameras.

What should I do to find the locations of the 3 cameras in the reference frame of day 1?
