To calculate "pixel/mm", principal point (in mm) and focal length (in mm) using openCV's "calibrationMatrixValues" function. The aperture width and aperture height are required as input. Aperture width and aperture height are not provided by manufacturer also. How to find those values?
Thank You :D

Thank You ..For reply
I also got the correct method.
If we have the Field of View(FOV) of camera in physical space (mm or microns) and sensor resolution (in pixels). Then mm/pixel is FOV /Resolution
(in same direction). The FOV is not dependent on monitor pixels, window pixels, Thus its better to use this method.
