Research on key techniques for multi-projector display wall

In this paper, the key techniques of multi-projector display wall are discussed. First we present an approach for geometric registration based on bicubic Bezier curved surface; Second, Focus on optimizing edge blending and achieving perfect visual effect, we propose a new edge blending paradigm, which based on spline interpolation. Comparing to the previous paradigm, our new paradigm is much more universal and flexible. To the best of our knowledge, this is the first method using spline interpolation for edge blending which can achieve perfect visual seamless.
