Projecting Video On Curved Surfaces

Posted by timothy on from the angle-dependent dept.

Jochen Bedersdorfer writes "According to golem.de, a research project in the area of Augmented Reality created a technology to project videos onto arbitrary existing screen surfaces, like wallpapered walls or window curtains. ... Quite awesome. Now I can use this ugly corner in my living room effectively."

  1. curved surfaces? by deathazre · · Score: 5, Interesting

    The problem with projecting an image onto a non-flat surface is you can only get it to look proper from one small area. Anywhere else and it's still distorted.

    Funny, I was just thinking about projecting video onto clouds the other day. You probably couldn't cut code using clouds as your gigant display unit, but you could probably watch some 'herbal movies' on them...

      Disney has already ventured into projecting videos on uncommon surfaces, such as the water spray screen in Fantasmic and the Grim Grinning Ghosts effect in the Haunted Mansion attraction.

  3. Not quite curved on a cricket ground.... by burnttoy · · Score: 5, Interesting

    At most cricket grounds over here (esp. for internationals like the current Windies tour) sponsor's logos are printed on the pitch (painted on the grass). BUT. The best camera angles for cricket are from a high up camera inthe stands. So the sponsors have to predistort their logos so that it looks good in a long, panoramic, high shot.

    I thought that it was quite clever when I first saw it.

      Let's not forget the anamorphic skull in Holbein's painting "The Ambassadors" from 500 years ago.

  4. One way to do it: by Janosh · · Score: 4, Interesting

    I haven't RTFA (/.'ed) A norwegian company who specialices in exhibition designs use a procedure to project images on walls in smal spaces, or curved surfaces. They build the room or sphere in a 3d program, and maps the wall with the images they will project. Then place the camera where the projector will be placed, and render. Now you have a video you can project that will fit the wall precicely.

  5. Disneyland by Therlin · · Score: 4, Interesting
    Disneyland has been playing with something that sounds similar to this.

    If you go here and scroll down halfway to "Sleeping Beauty Castle gets a new look", you can see a couple tests that Disneyland did to "paint" the castle. One painting it gold with a ribbon around it, and another one turning it into a US flag.

  6. Useful for odd projection angles? by ericzundel · · Score: 3, Interesting

    In our church, we are having issues mounting a projector in a place that is inconspicuous. Most of the inconspicuous places introduce too much of a keystone effect. That means that we will have to fix a (very expensive) projector to project with a special lens to one and only one screen. It might work fine when there is a large group, but if a smaller group wanted to use it in a more intimate setting, everyone will be sitting up front craning their necks. It would be neat if we could just point the projector at any surface and have it automatically correct for whatever distortion happened to be there.
