Autonomous Constructing Everyday Projected Displays

Abstract

This paper presents an autonomous geometric correction method to support constructing a projector-based large display for everyday use, which includes offline and online processing phase. The offline process is focus on an automatic, fast and robust approach for the geometric registration of projector-camera system. The online stage is mainly the implementing real-time image warping via modern graphics hardware to achieve the final corrected images without first acquiring geometric information of the screen’s surface. Since a simple checkerboard pattern is used to facilitate building the mapping of the corner correspondences of projector-camera image, and a perspective projection invariant rational Bezier patch is used to approximately represent the mapping, our method saves a lot of computing time and become easier and robust. Therefore, the achieved transformation can be used for online image warping for actual projection. As a result, a layman user can get a corrected image displayed on a non-planar surface for the point of view of the camera easily.
