Abstract

Abstract: This paper proposes a software method to construct a multi-projector display system. Based on the known geometric parameters of the projection curve surface such as radius, radian and the height of the circular-screen and the laser marking points, this method calculates the projection matrix of each projector to warp the image of each projector correctly. The Alpha blending and gamma rectification techniques are used to do the color blending. The experimental results show that the geometric warping and color blending effects of the seamless multi-projector display system are stable and effective.
