ABSTRACT:
A virtual view system uses raw imagery from cameras placed around a sporting arena to generate virtual views of the sporting event from any contemplated view point. The system consists of an optical tracking system, a virtual environment server, and one or more virtual view stations. The optical tracking system receives raw, 2-dimensional video data from a pre-selected number of cameras strategically placed around a sporting arena. The raw 2-dimensional data is then compartmentalized into data gates and processed via a series of software image processors into body state data assigned to each sports player or other targeted entity. The body state data is then passed to a virtual environmental server which generates body position information and visual models for transfer to a selected number of virtual view stations. Each virtual view station includes viewing software for rendering and viewing a virtual sports scene as desired. The view stations also control the viewing point of view of a virtual camera and output video data to a video production center so that video data may be transmitted and combined with other video output as needed. The system permits an operator to select a desired virtual view from the optional control center and transmit the virtual view images to a remote audience. Optional subsystems such as a control center and an archive computer may be integrated into the system to alter camera positioning, tether, focus, and zoom, and to store processed data for the sporting event and replay the data on demand.
