Are camera calibration files resolution agnostic?
Are the calibration parameters, generated by cameracalibrator.py, portable across arbitrary camera resolutions?
I'm attempting to calibrate a Raspberry Pi camera following the monocular camera calibration tutorial. The process seemed to complete flawlessly.
However, I ran the calibration routine with the image resolution at 640x480. Normally, I run the driver at 320x240 resolution to limit CPU. Can I use the same calibration parameters for 320x240 or do I need to re-run the calibration routine for that resolution and use a separate calibration file?
