Is that possible to only run extrinsic calibration

[Phimos]

can I fix the intrinsics and only run extrinsic calibraton for multi cameras?

Thank you very much for your interest in MC-Calib.
Yes, you can indeed run the calibration on the extrinsic parameters only; the solution is rather simple:

1. in the configuration file set fix_intrinsic: 1
2. set the path to your intrinsic calibration by replacing 'None' with your intrinsic calibration path in the parameter cam_params_path. This *.yml file should be of the same format as the output of MC-Calib (as introduced in the section "Output explanation" of the Readme). You can set random extrinsic parameters; they will not be considered

I hope this help! Please keep us in touch if this solution is working or if you need further support.
