I first obtain a json file containing all of the camera's information using calibration reader.py, and then I alter the distortion coefficient and the intrinsic matrix's values. After that I upload .json file using the calibration_flash.py script and test it using the calibration_reader script. Calibration reader read the right values, but when I use rgb preview, I can't tell the difference between before and after flashing the new values. I change values several times to values way to big from orignal to see diffrences, but still no result.
