first post so please be nice. I am doing an image processing project and my problem is now that I would like to know how big my digital image is in the real world.
I have: digital image: 336x256 pixel
camera focal length: 9mm
camara aperture: f/1,25
camera distance: 40m
pixel pitch: 17 micro m
FOV: 35° x 27°1.889 mr
Is there a way to calculate the real width and height of the image?
