Technology for Capturing 360 Degree Video
Inzite writes "EnterNetica R&D is working on a new spherical video technology for capturing and presenting full 360 degree scenes using a 180 degree lens, by adaptively predicting the camera's surroundings. Video extrapolation techniques have been proposed in the past, but this is the first time I've heard of an entire hemisphere of the video image being "guessed". The article also talks about feature film presentation using fully-immersive video in the future."

Here is google cache: thanks google.
I can't wait to see what movie theatres do with this technology. Maybe not our typical theatres, but yenno... like the one's at theme parks or something. I'm sure can make a pretty cool short movie with this.

It is odd seeing as there is a lens system in existence that can take 360 degree pictures. It uses a funky lens that goes all the way around like a donut IIRC, and the camera is mounted below the lens assembly... OH, here's one http://www.sony.net/Products/SC-HP/cx_news/vol34/f eaturing2.html and here http://www.bugeyedigital.com/product_main/036-0360 d.html , hell just type in 360 lens into google and tons of stuff pops up. Looks like the people marketing this are full of shit, and don't know anything about physics, or optics. Article is /.ed so I can't check out anything past the /. summary and what you said.
There were teams using Amigas doing this years ago. I recall 2 such products: ProVu, and Cosmo. ProVu was used for "interior design." And Cosmo was used by cosmetic surgeons.

There is comparable software that might be of interest along these lines ... check out:/

This lens does not offer you the possibility to record a full 360 image... There is no data about what can be seen below and above the viewer. What they do is creating a spherical image, not just a doughnut (which is what your "funky lens" is capable of).
The recorded image can then be viewed (my guess is by a kind of VR goggles) allowing the viewer full viewing freedom.
Next time you say somebody is full of shit, make sure you're not mistaken yourself.

You're confused by the terminology, I think. The guys in the article want to capture a full spherical image (which is possible with 180 degree fisheye lenses, taking 6 pictures at various angles, and stitching them together), those lenses you presented capture 360 degrees in a cylindrical fashion, also cool, but not what they want.
I've seen sperical quicktime files, a LONG time ago. They were neat.
Constitutional rights may be respected, repealed, or modified; but they must never be ignored.
At Siggraph this year, there were two similar systems on display. They are unbelievably cool.
1) Point Gray's Ladybug2 has five cameras mounted in a box about the size of, say, a stack of three decks of cards.
2) Immersive Media's system has 11 (!) cameras in a sphere about 2 inches on a side.
Both systems do real-time stitching of the multiple images into a panorama.
We're looking into them for the obvious motion-picture visual effects applications. The resolution (both spatial and dynamic) is not ideal for motion-picture work, but the ability to have an extremely small, lightweight, panoramic capture is a tradeoff that is worthy of pursuit. In the past (say, on The Fast and The Furious) we used six ARRI 435 cameras mounted to the side of a motorcycle, to the tune of several thousand dollars a day rental, hundreds of pounds of weight, and fairly compromised images in other ways (bad lens flare, extremely bouncy images.)

They've alread produced 360 degree lenses, and mounts for analog and digital cameras. The math's already been done to change this convex lens structure back to a linear view; it's been around for almost ten years. They have numerous licensees, and so 180 degree lenses seem like a cripple.

The issue that you encounter with taping two cameras together is that the depth of field is going to be different between them because the pupils of the cameras are at different points. When taking still panoramas from multiple shots, you can compensate by using a mount that swivels directly about the pupil of the camera (most mounts do not), but you can't so that with video.
The other awesome thing about this software is that you can apply it to prexisting footage. It separates the background, and stitches together a full sphere from an entire scene. As long as the camera pans around a decent amount, this technique gives you a spherical panorama from a traditional video source.
"Because Science" is one step from "Because old book". Try "Because of my experiment testing my falsifiable assertion".
You take a 180 degree fisheye lens, attach it to a camera, choose a virtual 180 degree line and rotate the assembly around that line. Then stitch the pictures together. You don't have to extrapolate nor do you lose any of the picture and have to "guess" as the article mentions. I am not sure what they are doing that seems "revolutionary", except maybe they have packaged the full unit and are showing it off. Either way, why are they having problems extrapolating to the hidden part behind the camera.
