[photo-3d] Stereoscopic Displays and Applications XII

["Steve Berezin" <sbere@xxxxxxxxxxxxx>]

Hi, I am covering the Stereoscopic Displays and Applications XII conference in San Jose for NSA's Stereo World and thought I would share some of my observations of the first day.

The first day of the Stereoscopic Displays and Applications had many interesting papers and videos. One paper involved high-speed digital stereo imaging at up to 1 million frames per second. The paper given by D. R. Snyder of the Air Force Research lab showed in nice 3D the cutting of a playing car with a moving bullet in frame by frame anaglyphic detail. A shot of golf shots and breaking glass in stereographic super slow motion were also impressive. 

Another interesting paper was "Stereo Mosaicing from a Single Moving Video Camera". This presentation not only involved stitching together frames taken from a video camera to make a 360 degree stereo panorama, it was demonstrated in real time while the presenter was giving his paper. He simply waved a digital camera attached to his laptop computer in front of the audience and before our eyes produced a 3d anaglyphic image of the audience on the projection screen in glorious 3D. 

One interesting presentation involved using 3D imagery in a Heads-up display for airplane pilots to de-clutter the control panel. It was popular with pilots except that the fact that the green phosphors of the display failed to extinguish soon enough to prevent ghosting with the included shutter glasses. Another involved a complex array of layering used to create a "Multi-media Ambiance Communication". Images far from the viewer were presented in a panoramic non-stereoscopic method, middle distance images were layered and close-up images were rendered in 3d from computer models. Human subjects were scanned from a whole body scanner and then made to fit a preformed model. 

Other presentations included optimizing of polarization materials, field refresh rate issues, use of stereo imaging in treatment of ‘lazy eye’ and DirectX imaging of stereo images. Later, videos were shown using the rear projection screen in the theatre. They included a sick clown video, a new Ray Hannison Video and some of the Dynamic Digital Depth video conversions. Of a special note was a Korean Video that was called ‘The Pearl Sea’. This was a bit of a soap opera about a pearl diver who leaves home to become a diver for a large public aquarium. This allows for many nice underwater shots interspersed with nice scenic terrestrial shots.

Tomorrow’s presentation will mostly detail auto-stereoscopic displays.
