Monocular vs. Binocular

Existing work has been done on recovering 3d positions from monocular images, with the camera facing the golfer during the swing. We are wondering if techniques operating on a monocular view would be able to accurately distinguish the following positions. Notice that from face-on view, the body positions are very similar, and the differences in wrist angles and length of the club (due to foreshortening) are not drastic. Looking at the same three positions from the down-the-line angle shows that the club is actually in drastically different positions, and these differences are critical when examining and analyzing a golf swing. We will need to investigate how existing monocular view algorithms perform on these sorts of test cases.
