i am asked to show physical constraints of camera parameters (both extrinsic and intrinsic) in matlab. i need to show the focal length of lens, size of pixel, position of principal point, orientation and position of camera etc. how can i show that in matlab? i can understand showing pixel of image but how do i show size of pixel, focal length of camera in matlab? i do not have any clue about what is direct parameter calibration method. please let me know how to solve this

I find it exceedingly doubtful that an instructor would ask you to use a method that has not been presented in class, or at least give you a reading reference if it has not been.
