Abstract
Large plane displays are often achieved by combining tiled imaging elements, which give the appearance of a single, seamless display. However, this is difficult to realize in practical use, since differences in color will make the tiles dis-tinct even if the geometric calibration is perfect. The paper presents an approach of color calibration using cubic B- spline. According to the theory of cubic B-spline, we construct the color transfer function of each projector. This ap-proach reduces the color and photometric non-uniformities to achieve seamless tiled multi-projector display well. Finally, we propose the difference between blending region and overlapping region which can help to achieve a better effect of alpha blending.

Summary
With the continuous development of the projection display technology, the large plane multi-projector displays technique has been widely used in various fields to meet people’s increasing demand for high-resolution display. Even if the geometric calibration is perfect, it still can not achieve seamless tiled multi-projector display, because of the differences in color. 2) Application Dependent a) Photometric Variation Due to Overlapping Projectors; b) Photometric Variation Due to Non-planar or NonLambertian Display Surface Taking these causes into account, the work of color calibration is carried on in three aspects: calibration within each projector, calibration between the adjacent projectors, and calibration in the overlapping region of projectors. The problem is the professional instruments are usually too expensive to be afforded The latter method greatly reduces the cost, but it brings the drawback of information imprecise at the same time. This paper presents an approach of color calibration to achieve seamless tiled multi-projector display. The projector’s color transfer function for each channel is constructed using cubic B-spline
