] With video projectors images can be displayed that are
] larger than the devices themselves. However, we have to
] give up living space and ambience to set up artificial
] canvases that have to be as large as the desired image.
] Smart projectors are able to display correct images onto
] arbitrary existing screen surfaces, like wallpapered
] walls or window curtains. Thus it can function without an
] artificial canvas and consequently leaves a bit more
] freedom to us in the decision on how to arrange our
] living space. Our smart projectors combine camera
] feedback with structured light projection to gain
] information about the screen surface and the environment.
] The calibration of such a device is fast, fully automatic
] and robust, and the correction of video signals can be
] achieved in real-time. Neither geometry information nor
] projector or camera parameters need to be known. Instead,
] the entire calibration and correction (geometry and
] color) is done on a per-pixel level - supported by
] modern pixel shader hardware.
