Multi-Projector Display Systems on Curved Screens with an Automatic-Calibration

Abstract

To achieve a deep sense of immersion or the feeling that one is actually present in the experience with a training or research simulator, high-resolution and a wide field of view are indispensable. Multi-projector technology has been under consideration in recent years. This technology allows the generation of wide field of view and high-resolution images in a cost-effective manner. Conventional methods, usually involve lenses for optical correction of the distortion, has been widely used. However, they have problems such as limited screen size, complicated adjustments of projectors and luminance compensation. To solve these issues, we developed an automatic calibration method, “virtual camera method ” , which yielded high-precision calibration regardless of the camera position based on computer vision. In this paper, we propose a "multiple-shot calibration" that is a calibration method for applying "virtual camera method" to a wide field of view screen.
