Hitachi demos 3D real-world object projector

Oct 05, 2011 by Bob Yirka weblog

(PhysOrg.com) -- In a feat of technical wizardry combined with several doses of panache, Hitachi has demoed a 3D projector that can project images onto real-world objects in stunning fashion. For the demo, a 3D image of a bird hatching was displayed on an artificial egg that was cradled in an artificial nest. But that’s not all. Viewers looking at the demo see the bird as a hologram, in that as the viewing angle changes, so too does the view of the image, just as it would were you to be watching a real bird. The demo brings to mind Princess Leia, in Star Wars, delivering her message via 3D hologram to Obi Wan Kenobi.

The demo, shown as part of the Combined Exhibition of Advanced Technologies (CEATEC) trade show, the Japanese equivalent of CES, at the Makuhari Messe convention center just outside of Tokyo, was meant to show the progress that Hitachi has made in developing 3D projecting devices. Called Full-parallax 3D Display Technology, it looks like hologram technology, but isn’t. Instead it utilizes multiple cameras to capture the image then displays it using a group of 24 projectors, transparent mirrors and computers to project the image down onto a real three-dimensional object, such as an egg. In this respect, the technology is truly unique.

When a viewer looking at the image moves up or down or left or right, what they see changes to suit the viewing angle. And if that’s not enough, the projected image can be viewed by multiple people from multiple angles, and everyone sees it as they would were there an actual real-world object sitting there. Also, if the object is moved around a little, the system compensates for it automatically.

The system has a 60° horizontal and 30° vertical viewing angle and Hitachi reps report that it will have a resolution that is 1.6 times higher than anything shown before, though there are reports that Sony is working on a similar system so that boast may not last long.

In addition to its use as a tool to show off its coolness factor, believes that the could be used by design engineers, digital signature apps and perhaps as a training device in the manufacturing or medical arenas.

What an informative diagram!

On a more serious note, I can see this being useful for virtual assistants at stores...basically a mannequin with a 3d human projected face overlay.

Think of how many jobs you could cut (more profit for execs) if GAP or whatever had the same AI assistant in each store!

Let me guess. You have the solution and people simply won't listen, because they don't know better as they are obviously not as smart as you are.

Big happy happy egg fun time !!!

Not a wide range of viewing angles, couldn't do moving full size people, but still neato torpedo all the same.

Obviously highly impractical outside of specialized circumstances, but still cool.

I think though, that this is a proof of concept for something else. It is a clever adaptation/evolution of current 3d technology (It's probably using a form of parallax in conjunction with the projector and the three dimensional surface of the screen.)

It could be interesting. Think of a 'rear projected' screen that is ten feet in diameter, with 6 projectors. You could walk around it entirely.

It has some potential to be re-engineered into some neat applications. Engineering, niche entertainment, pron. (Especially the last one)

Most people come to reject Randite Ideology as childish after a few years of adulthood.

Others, like yourself, remain intellectual failures their entire life.

Death will be the only cure for you.

Very nice innovation from our former enemies, the Japanese. They surpass us in certain ways. Thank goodness they are our friends. Japan is truly Capitalist and they don't have such great numbers of their population on welfare checks as we do. In Japan it is a dishonor to each individual and his/her family to not take full advantage of their educational system. We can learn a lot from them.
However, I doubt that I will ever have use for such a device in my home and I'm not a designer or engineer. I do foresee a clever use for it in the training of surgeons in the operating room.

You are a very rude person. I seriously doubt you're an adult as you obviously haven't learned how to behave yourself in a proper manner. Learn to control yourself. The last thing we need is another trigger happy socialist.

Unfortunately, I can't check those links from work :(

But let me append my statement, I believe that this kind of display will be useful in certain situations, but I do not believe it will become a consumer product anytime soon.

Who's talking about gun control? I think you're confused. Oh and advocating socialism makes you a socialist. That is as far as I know the very definition of it.
