A new development of German scientists in the near future will make it possible to watch 3D broadcasts in real time without glasses.
Today, 3D TV owners are content with a limited list of gears, since to receive 3D images, the footage needs to be further processed, so it makes it impossible to watch 3D broadcasts in real time.
Technology without the use of glasses, called autostereoscopy, has already been applied. It is based on the use of lenses or a parallax barrier, so that the left and right eyes see a different number of pixels, which creates the illusion of volume. The drawback of this method lies in the high cost and fixed distance between the viewer and the TV, the fatigue of the eyes.
Another method consists in simultaneous shooting of an object by a large number of cameras, which are installed at different angles, as a result of which images are poured onto each other, creating a 3D image. And the more cameras, the bigger the picture, but it's not practical, says Frederick Cilli (Fraunhofer Institute named after Heinrich Hertz).
Scientists have developed a stereoscopic analyzer (STAN), which can process captured footage in real time and create the effect of simultaneous shooting of 25 cameras. This system is a tablet computer on which software is installed to convert the signal into a stereo format. Unfortunately, the conversion speed is not yet sufficient for a full-scale broadcast of 3D transmissions, but Frederick Cilli claims that this problem will be solved in the near future.
