Math, Not Cameras, Can Create 3D
by Linda Hardesty

3D promises to be a big topic at Cable-Tec Expo in Denver this week. CableLabs and the SCTE are co-sponsoring a 3,400-foot 3D TV Pavilion with demonstrations from some top consumer electronics manufacturers. (For more, click here).

Considering that CE makers such as Sony, Panasonic, and LG Electronics are participating in the 3D Pavilion, there will probably be an emphasis on their 3D-ready TVs.

But the TV set is just part of the puzzle. Video providers need to ensure the necessary throughput to deliver 3D. And programmers need to create more content in 3D. It’s a bit of a stalemate, with all parties waiting for consumer demand to justify the business case.

And the technology itself is costly. It’s expensive to shoot video using two cameras for every view – a left eye view and a right eye view - to create the stereoscopic 3D effect.

Maths say 2D cannot be converted to 3D automatically because missing data cannot be retrieved out of nothing.
But magic is often more interesting than science... unfortunately

cool concept.

Theoretical question: Because a football field, for example, is always the same size, with evenly spaces reference points all over the field, it would be possible for a human, by hand, to go through football game footage and give each object, by highlighting either individual objects or entire areas, a specific Z depth and use that to create two different sides? I know it would be absurdlt time consuming, but it is possible, right?

Second, in a highly controlled situation (for example, a footbal stadium again), would it be possible for a computer to do the same thing as the human in the above situation?

It seems possible to me, just absurdly hard. Anybody wanna enlighten me if I am wrong?

you are correct. What "professional" 2d->3d conversions consist of is teams of 3d modellers make 3d models exactly in the same positions as the actors/objects and use those to create depth by using them for the displacement for the second eye- way too time consuming/redundant when you can just shoot new stuff using 3d cameras
