Abstract
Multiple electronic displays are arranged to define an ensemble of the user's choosing. The processor generates and displays a uniquely encoded emblem encoding a unique identifier for that display. A camera captures at least one image of the ensemble so that the encoded emblem for each display is captured. The captured images are then processed to extract the following attributes: a) unique identifier of the display; b) position of the encoded emblem relative to the reference coordinate system; and c) pointing direction of the encoded emblem relative to the reference coordinate system. The processor collectively processes the attributes for each of the emblem images to compute for each display a transformation matrix that selects a portion of the image data for display on that monitor and performs pointing direction correction so that the information presented on that display appears spatially consistent with the information presented on the other displays.
