    Inexpensive Immersive Projection

    Low cost 180 degree visuals? Perhaps.
    [media]http://youtube.com/watch?v=HMB8YVbyicE[/media]

    From the recent Virtual Reality Conference ( VR 2008 in Reno, NV, USA, March 2008 ) comes a low cost projection project which could help this hobby realize greater than 180 degree visuals. I'm hoping it's not blurry or stretched, but the video looks promising.

    A quote from the paper:

    "Our goal is to build an immersive projection system that meets
    these requirements: uses minimal, affordable hardware; takes advantage
    of existing surfaces for display; requires minimal setup and
    configuration; produces a large field of view, greater than 180 degrees;
    requires only a casual arrangement of system components;
    avoids determining display surface geometry; supports real-time interaction."

    A bio of one of the authors, and a link to the project paper in PDF.

    They use a library called OpenCV (open computer vision library) for corner detection which helps to automatically calibrate the display. http://sourceforge.net/projects/opencvlibrary/

    Looks promising. I'll have to tinker with this library.

    That is a very interesting little bit of info.
    I wonder what this puppy costs.

    Cost of 180 degree display

    If you read the paper, they say the total cost minus the projector and computer was around $350. Of course, I would want a seamless half dome screen which would be difficult to make.
