  • Patent number: 6084979
    Abstract: A method of virtualizing reality, i.e., a method of creating virtual reality from images of a real event, is comprised of the steps of capturing a plurality of images of each time instant of a real event using a plurality of cameras positioned at a plurality of angles. Each image is stored as intensity and/or color information. A suitable internal representation is computed from these images and the information regarding the camera angles. An image of each time instant may be generated from any viewing angle using the internal representation of it. The virtual viewpoints could be displayed on a single TV screen or using a stereoscopic display device for a true three-dimensional effect. The event thus virtualized can be navigated through, and interacted with, any virtual reality system.
