We understand that that was used as an example, but how do we find that number? You have to have a way to find the exact number (you can't use examples for the real thing). How does the camera "show" the width of the rectangle is 56 pixels? If I step 10 feet farther back, obviously the target rectangle will NOT measure 56 pixels anymore. How do find out what the NEW width is?
