I came across this demo by Fox sports:
Where they show a player's view in a 360 space. Very smooth and nice.
I was wondering how do they achieve it without any cameras attached to the player?
One approach that came into my mind was using a multi-camera setup and convert 2D images to 3D using a stitching mechanism as a post processin. Is it what they do?! What are other approaches that we can do it?
