Video system and methods for operating a video system
First Claim
1. A method associated with a moving target within a dynamic scene, comprising:
- reading parameters of a first variable pointing camera system;
determining parameters for a plurality of other variable pointing camera systems based on the parameters of the first variable pointing camera system and mapping data for the camera systems, wherein the first variable pointing camera system and the plurality of other variable pointing camera systems are positioned around the scene, such that, at a point in time, each of the variable pointing camera systems is aimed at the target and a size of the target in an image from each of the variable pointing camera systems is substantially the same; and
controlling the plurality of other variable pointing camera systems based on the parameters for the plurality of other variable pointing camera systems wherein the mapping data includes initial calibration data established when the plurality of slave variable pointing camera systems are installed at the dynamic scene, comprisinginitial calibration data regarding the geometric relationship of the camera systems to the scene;
initial calibration data regarding the relationship between the zoom and the angular field of view for each camera system; and
initial calibration data regarding the relationship between the focus and the range to target for each camera system, andfurther wherein a first slave variable pointing camera system is taken off line during filming of the dynamic scene, re-calibrated to adjust the initial calibration data, and returned on line during filming.

Abstract
A multiple camera video system and methods for operating such a system. The system may include a plurality of cameras located around a stadium, athletic playing field or other location. The cameras are remotely controlled in a master-slave configuration. A camera operator at a master pan head selects one of the plurality of cameras as the current master camera and utilizes the master pan head to adjust the telemetry and zoom of the master camera to follow the target object. The telemetry and zoom parameters of the master camera are then used to calculate corresponding telemetry, zoom and/or other parameters for each of the plurality of slave cameras. Video captured by each of the cameras is stored for the production of replay video feeds or for archiving. The replays may be capable of “spinning” through the video feeds of adjacent cameras in order for the viewer to get the sensation of revolving around the target object. The multiple camera video system also includes methods for calibrating the system.
