View a real live game with the same kind of controls and camera angles you can use to watch a 3d computer football game on your computer.
Track multiple (10+) cameras located around a sporting event ( say a football/soccor match). Use real-time computer analysis to distinguish players and the ball
from the field and generate a 3d location and cutout image. Regerate the 3d positions in a computer and then "skin" them using the best available live image (or combination of images).
Much of this technology is available now and the power to do it in realtime ( allowing some delay ) is close enough that someone is probably working on it already... I know I'd love to be!
related areas:
- Fox hockey puck ( and the more economically successful virtual 10yard down line in US football)
- Current 3D VR and artificial intelligence 3D image processing work ( Intel labs and many others)
- video compression technologies ( MPEG, Internet Video a la Real Networks and Microsoft)
There are some Dutch guys who were doing 3d un-skinned models of Football ( Soccor) goals and posting them on the net a day later. It's the closest thing I've seen yet to this idea.

Virtual Spectator is good to go on this - America's Cup, road races, etc. have been the targets thus far.
It's considered good form to leave your email address on your profile page: press on your nic, and that'll take you there. You can tell us all about your elf 'n' stuff there too. |

Sky did somethign similar for one incident in the Spurs v Fulham game (football/soccer), to prove that the referee had been unsighted when he awarded a penalty and sent a player off. |
|
| |
The virtual camera, showed the posiitons of all the players and swopped around to show diferent POVs. Very neat. +1 |
|
| |
Sounds hideous. Watch the game. Enjoy. Then argue about it with your mates afterwards. That's what sport is about, not arsing around with camera angles and pointless statistics. |
|
| |
I think I know a better way to do this, and I've toyed with posting it here for some time. But it'll have to wait. |

I've seen this done during a hockey playoff game. They had placed 36 cameras around the periphery of the arena, all programmed to point to a chip in the hockey puck. This was used to zoom around in a 'bullet time' style, twisting the arena around to get the best look at the action. |
|
| |
Rather than translating everything into video game format, and worrying about translating field action into game play, just place three cameras (normal, telephoto, extreme telephoto) to each of those 36 positions. Then you'll get live view-from-any-angle footage. |
|
| |
But those views are still from the sidelines. I rather like this, for it's helmet-cam perspective and view-from-anywhere potential. I want the puck / ball viewpoint. Surprised I haven't seen too many commercials explore it. |

The Virtual Spectator
mentioned by thumbwax half
way there ( it updates a player
position, not image, in a
modeled playfield - which isn't
updated at all ). Commercially
viable idea which I'm sure will be
more commonly done with the
advent of the ps2 and xbox
online services. |
|
| |
Since posting this half-baked
idea I've come across a company
closer but with morphing
between camera angles instead
of decomposing/recomposing.
Close enough for most
applications but still not what I
was hoping for. They call it
"Virtual Viewpoint"

Better yet: A research paper
oriented towards video
compression is much closer.
They have implemented their
system with results similar to
the game graphics of 2000.
"Multiview Video Sequence
Analysis, Compression, and
Virtual Viewpoint Synthesis" IEEE
Transactions on Circuits and
Systems for Video Technology,
Vol.10, No.3, April, 2000.
Hmm.. Maybe it's in MPEG4
already?? |

More: Sarnoff Corporation's
security product
"VideoFlashlight" Neat overlay
of live video on models of your
very own compound. |
|
| |
Then there's the BBC's
Prometheus project which I'm
sure has contributed to some of
the visual effects they have
used in documentaries. |

Almost Baked and Delivered...
I'm guessing 3D reconstructive
TV with virtual viewpoints on
your Playstation 3 ! |
|
| |
And why aren't we seeing
broadcasts with updating of 3D
models on your PC via the
internet ( a la Virtual Spectator )
in the meantime?? Heck.. they
already produce highly accurate
and detailed models of golf
courses, stadiums and even cities
for games... |

20 years later... Oct 1, 2023: "While the traditional NFL game broadcast will be streamed on ESPN+, so too will the Toy Story Funday Football alt-cast, a fully rendered, Pixar-ified version of the action. Viewers on Disney+ and NFL+ will have that option as well, as Sony-owned Beyond Sports takes live game tracking data to recreate game play." - from sportsbusinessjournal.com article. |
