Enjoy 3D films without glasses - Techsemo

A new technology has been developed that will make it possible for viewers to enjoy 3D programmes without 3D glasses. Though prototypes of these television screens already exist, consumers will not have to wait much longer for the market introduction of these autostereoscopic displays. Nevertheless, the content might be a bit problematic, The 3D movies currently available on Blu-ray are based on two different perspectives, i.e. two images, one for each eye.

However, autostereoscopic displays need five to ten views of the same scene (depending on the type). In the future, the number will probably be even more. This is because these displays have to present a three-dimensional image in such a manner that it can be seen from different angles – indeed, there is more than one place to sit on a sofa, and you should be able to get the same three dimensional impressions from any position.

Researchers at Fraunhofer Institute for Telecommunications, Heinrich-Hertz Institute in Berlin recently developed a technology that converts a Blu-ray’s existing 3D content in a manner that enables them to be shown on autostereoscopic displays.
“We take the existing two images and generate a depth map and that is to say, a map that assigns a specific distance from the camera to each object,” Christian Riechert, research fellow at Heinrich-Hertz Institute said.
“From there we compute any of several intermediate views by applying depth image-based rendering techniques. And here’s the really neat thing: The process operates on a fully automated basis, and in real time,” Christian Riechert said
Previous systems were only capable of generating such depth maps at a dramatically slower pace and sometimes they even required manual adaption. Real-time conversion, by contrast, is like simultaneous interpretation. The viewer inserts a 3D Blu-ray disc, gets comfortable in front of the television screen and enjoys the movie without the glasses.

Meanwhile, a hardware component estimates the depth map in the background and generates the requisite views. The viewer is aware of nothing: He/she can fast forward or rewind the movie, start it, stop it and all with the same outstanding quality. The flickering that could appear on the edges of objects and something that happens due to imprecise estimations is imperceptible here.

The researchers have already finished the software that converts these data. In the next step, the scientists, working in collaboration with industry partners, intend to port it onto a hardware product so that it can be integrated into televisions. Nevertheless, it will still take at least another calendar year before the technology hits department store shelves.

This will be unveiled at the IFA trade show in Berlin from August 31 2012 to September 5 2012.
