Let's think a bit out of the box... First, the compass does not need to be parallel to the Earth. If it's a ball compass, it can rotate freely and you 'just' have to recognize the orientation of the ball. But, even if you decide to go with a classic pin compass, say, because of size considerations, it still doesn't mean you have to be parallel to the camera - just that you need a small mirror or prism on the camera. Massive effort for questionable results ? Absolutely, but not impossible
