I am thinking about some technology for 3D video which
can improve webcam video quality, so it looks more realistic
and amazing. Is it possible to have 3D video?

You're the one thinking about technology - you tell us.

Any thoughts would be greatly appreciated.

Other than the classic red/green filter approach I'm not aware of any
"practical" technology for moving 3D or pseudo-3D images.

(and polarised/LCD shutter variations on the same theme. Ahem.)

When I was in Japan about 5 uears ago Sony was doing an amazing 3D video
demo with polarized glasses and twin-Camera/twin=projectors. Unbelievably
crisp and the #D effect was tremendous.

Yes, but you need two projectors. Or alternatively draw two small (slightly)
different scenes onto your screen with the distance of your eyes and move
your head very near to your screen. Then you basically have a cheap version
of these 3D helmets / glasses.

They can be nice and detailed (tend to also be monochromatic, though) but
they're static.

In principle you could get a sequence of these on a strip of film and show
them in the same way as a regular 2D film, but you'd need a rather fiddly
viewing arrangement (as you don't "project" holograms in the same way as 2D
films) plus you couldn't record in anything like real time either.
Recording would have to be more a stop-motion/Wallace & Gromit sort of
affair.

Also in principle you could have a _very_ high resolution LCD panel in the
path of a laser beam and switch that dynamically to set up an interference
pattern that generates a hologram (with sizeable computer working out the
pattern needed for a given scene). In practice that's just not possible
given current LCD technology.

"Hologram projectors" which you sit in the corner and have generate an image
in the middle of the room are 100% sci fi (despite having appeared as plot
devices in all sorts of "regular" TV shows). Not only is there no
technology to do what they do, there isn't even a theoretical model for how
you could go about designing that technology.
