In fact, we don't have diferent cameras for each project, it would be nice to automatically save cameras used and ask user if he wants to reimport parameters saved for a camera having the same aspect ratio and resolution (frame type, pixel pitch if not present in exifs, focal length if not in exifs, rolling shutter parameters, ...). Calibration is another thing, but we could save it manually and have the choice to import a certain calibration matching the detected setup.
