I got errors after running ./calibration-graph-cli for calibration with 5 cameras.
The following contents are part of the outputs from ./calibration-graph-cli for one of the 5 cameras, “camera-2”. camera-2 is a fisheye camera with 200 degree FOV.

Note: fixing principal point, D, and E for ocam camera
Can anyone help with solving those errors? What are the causes of those errors? I followed the steps from the tutorial in the document.
