Image warping implemented by a simple array of projectors

In this paper we propose to implement image warping by two projectors. The screen that the images are projected onto is assumed to be the lateral surface of a cylindroid with known lengths of major and minor axes. A blending function that smooths the overlapped projection area is used. The geometric...

Description
Summary:In this paper we propose to implement image warping by two projectors. The screen that the images are projected onto is assumed to be the lateral surface of a cylindroid with known lengths of major and minor axes. A blending function that smooths the overlapped projection area is used. The geometric correction model for the convex type of surface is derived. In particular, the model is presented in the form that might result in an easier hardware implementation. Experiment results are presented at the end of the paper to illustrate the effectiveness of our approach.
