Hello everyone.
I have several Oak-D Pro W. Currently, the cameras have the specHfovDeg EEPROM value set to 71.8°, which is the same as the standard Oak-D Pro. I haven't calibrated them myself, so I'm assuming these are factory settings. Is this value correct? It describes the FOV of the sensor alone or the sensor-lens system? The OAK-D-PRO-W.json file gives a value of 127° and is consistent with the documentation, so I assume that after recalibration, the value should be set to just that.
If this value is irrelevant to proper operation, I'd prefer to avoid recalibrating all my cameras.

The Oak-D Pro uses an IMX378 sensor in its RGB camera. depthai/calibrate.py sets the resolution of this sensor to 4K, while according to the specification, it is 12MP.

When converting to 4K, the image is cropped, so we don't use the entire VFOV.

What is the reason for this conversion? Can changing the calibration resolution cause problems with the Oak-D Pro W?
