When calibrating a camera with a pinhole model, the calibration-graph-cli estimates the distortion with 5 parameters
When exporting the graph to rig, only the first three are exported to the rig:
“distortion”: "-3.04611116647720e-1 1.96133777499199e-1 0.000000000000000 ",
This seems like a bug, especially because the value of the last parameter is significant (-0.1485759731521464)
- Which of the above coefficients correspond to the radial and which to tangential distortion?
- In dwPinholeCameraConfig there is support for a single distortion polynomial (I presume radial distortion)?
- If the calibration estimates both radial and tangential distortion, it seems wrong to use just radial distortion when rectifying the images.
I am attaching the related files, please check the CALIBRATION_LOG.log for the calibration log with appended calibrated graph and a rig file:

Thanks in advance!
