Japanese 3D display goes the distance

University of Tokyo scientists create a 3D display with an image depth of several metres.

A 3D display that does not require special viewing spectacles could benefit television, computer gaming and even air-traffic control say its Japanese inventors. Based on an array of small lenses, the device generates a 3D image with a perceived depth of several metres for viewing with the naked eye. (OPTICS LETTERS 30 613)

The display uses so-called integral photography to generate its 3D images. A computer divides up the image into pixels that are either printed on photographic film or shown on a flat screen display. When passed through an array of lenses the result is a 3D image with a depth of 5.7 m or more in front of the display and 3.5 m or more behind the display.

“The integral photography technique has none of the inherent eye-straining problems associated with continuous viewing of binocular stereoscopic displays,” University of Tokyo scientist Hongen Liao told Optics.org. “It is an ideal way to display autostereoscopic images.”

Up until now the success of this technique has been limited by the accuracy of the lens array, which here is composed of 6 mm diameter glass lenslets arranged in a 35 x 35 hexagonal layout. As Liao explains, even a small error in the lens’ arrangement can cause image overlap and blurring, which limits the precision and depth of the 3D image.

“Most of the autostereoscopic displays only have an image depth of several centimetres,” said Liao. “To the best of our knowledge, there has been no report about producing an image with a depth of several metres.”

Liao and his colleagues have found a way of preparing images that allow them to be viewed at long distances. Firstly, a computer pixelates the image to match the 3D display’s lens array and projects this image on to a screen. The researchers then use the 3D display’s lens array to capture this view on photographic film, creating a reference image that self compensates for any lens distortion or misplacement.

“Our method enables a display device to present virtually deviation-free and distortion-free 3D images,” said Liao. “We are now developing an animated long viewing distance integral videography device.”

Our jobs will soon be phased out.


#3

Yeah, good call pongball. 3D display, dang, that’ll replace animators.


#4

:surprised i’m with spike on this one


#5

humm… wouldn’t widely available 3d display technology create MORE jobs for us?


#6

no

I have to agree w/Lordiego01.
If this takes off… think of the content that would be possible. Games would be incredible, music videos would be insane and imagine 3D movies:bounce:


#8

how would a 3d display kills our jobs?


#9

Yea, I didn’t get that one either. More 3d = more jobs.
Oh, unless Pongball is a 2d artist :twisted:

Woohoo to 3d!

correct me if I’m wrong, but I THINK this is sarcasm.


#11

I think thats awesome personally.I can see this as a good thing for 3D.:thumbsup:


#12

all good, but just think how far away you’d have to sit from the screen…!
what about all the 3D guys who work freelance from their tiny boxroom, constantly getting a vertex in the eye?!?

splines can be pretty sharp! ouch! :argh:


#13

games will HAVE to go this way if they are to be more immersive…regardless of this or any other technology the 2d barrier will be surpassed.

and that could only mean creating more immersive content traditionally or digitally.
i’m sure the posts above were in jest.

it’s good to be doing what were doing and it will get better. :slight_smile:

You have to wonder though…

They are biased of course (IMHO) and are wrong too :smiley:

Nah, serious. But sorry about the rude tone…it was light hearted, I swear. Too many Boags, it was.

I guess your assuming tha this machine can take a 2D image and project it into space as a 3D object? Well, I don’t know about you, but here in Australia such witch craft would have you burned at the stake.

Love the way the Japanese mind works -

step one : create revolutionary, groundbreaking tech

step two : mount it one a chair

And Wiro, how’s the ship?
