摘要：We propose a method for precise overlapping of projected images using multiple steerable projectors. When steerable projectors are controlled simultaneously, two problems occur: (1) because the flatness of the projected planes is not suited to the real environment, each projected image from each multiple projector that is calibrated with just a part of the plane cannot always be located to the same position as that of an image from another projector, even when the images are intended to be located at the same position; and (2) because the projectors run asynchronously it is impossible to display a moving image by precisely tiling or overlaying the multiple projected images. To overcome this (1), we propose a method that preliminarily measures the misalignments through every plane in the environment, and hence displays the image without misalignment. For (2), we describe a method for the synchronization of moving and scaling between multiple projections.
