摘要 Advances in display and input technologies have led to growing desire for creating a more immersive visual experience in interactive display systems. Research on constructing a large-scale, high-resolution display environment based on multi-projector mosaic has also become increasingly important to meet the cost-effective consideration. In our previous work, we had developed a system called i-m-Top, which integrated one steerable fovea projector for high-resolution projection and another fixed wide-angle projector for low-resolution. The touch-sensing is on the basis of diffused illumination and analyzed by computer vision approach. In this paper, we propose a fast, low-cost method for automatic projector calibration with the assistance of one color camera, to eliminate both the keystone effect and misalignment of the projections. Structured light patterns are projected to construct the geometric relationship between projectors and the projection surface, and then pre-warp the images so that they appear undistorted as a result. As opposed to manual calibration which is a tedious task, our approach not only saves time, but also reduces human-effort effectively.
