The applications of this are interesting to say the least. Something i am currently working on is using fisheye images of the sky to predict cloud motion and to then estimate solar PV power output in the short term i.e. one to five minutes out. It sounds simple but it isn’t yet even a child can observe cloud motion and predict to some degree when the disc of the sun will be obscured. Part of the inaccuracy is in the distortion caused by the fisheye lens. I would be interested in seeing how well this works for subjects at infinity i.e. a fisheye lens pointed at the sky.
