Low-Cost Multi-Projector Curved Screen Displays
Current systems for high resolution curved screen displays are expensive and target high-end applications. We present a technique to create a low-cost multi-projector curved screen display using a parametric approach called the quadric transfer. This parametric approach has several advantages that are exploited to allow for flexible system configuration and the use of low-cost off-the-shelf com...
متن کاملQuadric Transfer for Immersive Curved Screen Displays
Curved screens are increasingly being used for high-resolution immersive visualization environments. We describe a new technique to display seamless images using overlapping projectors on curved quadric surfaces such as spherical or cylindrical shape. We exploit a quadric image transfer function and show how it can be used to achieve sub-pixel registration while interactively displaying two or ...

Curved screens are increasingly being used for high-resolution immersive visualization environments. We describe a new technique to display seamless images using overlapping projectors on curved quadric surfaces such as spherical or cylindrical shape. We define a new quadric image transfer function and show how it can be used to achieve sub-pixel registration while interactively displaying two ...
متن کاملDynamic Shadow Elimination for Multi-Projector Displays
A major problem with interactive displays based on frontprojection is that users cast undesirable shadows on the display surface. This situation is only partially-addressed by mounting a single projector at an extreme angle and prewarping the projected image to undo keystoning distortions. This paper demonstrates that shadows can be muted by redundantly-illuminating the display surface using mu...
متن کاملAd-Hoc Multi-planar Projector Displays
High-resolution portable projectors have become commodity items now. But it is not always possible to find a display area where the camera can be properly aligned so that an undistorted image be seen. More so, a flat area of projection itself might not be available. We present a method to project an undistorted image using a digital projector on a piecewise-planar display area. Using a the proj...
