Setting a reference camera when exporting extrinsic parameters

[yuvalg1987]

Hi,

I working with 3DFlow for research purposes and I need to export the cameras extrinsic parameters. Ideally I would like that one camera (reference camera) will be located at (I|0) and all other cameras
will have their extrinsic parameters relative to it. Is it possible to do so without writing code?

If it not possible the following equation should solve it:
X1 = R1 * Xw + t1
X2 = R2 * Xw + t2

R1to2 = R2 * R1^T
t2to1 = t2 + R1to2 * t1

X2 = R1to2 * X1 + t2to1

would like to hear some feedback about this option.

Thanks
Yuval

Hi yuvalg,

you can export camera positions from the export menu in Pro/Aerial. If you need to have a specific camera at a specific position, consider using camera constraints when starting the reconstruction
