Method of Automatically Forming One Three-Dimensional Space with Multiple Screens

摘要

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.

1. A method for presenting information across multiple electronic displays, comprising:
arranging multiple electronic displays to define an ensemble; generating and displaying on each display a uniquely encoded emblem that encodes a unique identifier for that display; capturing at least one digital image of the ensemble so that the encoded emblem for each display is captured; defining a reference coordinate system corresponding to the space occupied by the ensemble of electronic displays; processing each of the captured encoded emblem images to extract the following attributes:
a) unique identifier of the display;b) position of the encoded emblem relative to the reference coordinate system; andc) pointing direction of the encoded emblem relative to the reference coordinate system; supplying the information to be presented as image data to be displayed across the ensemble of displays; and collectively processing the attributes for each of the encoded emblem images to compute for each display a transformation matrix that selects a portion of the image data for display on that monitor and that performs pointing direction correction so that the information presented on that display appears spatially consistent with the information presented on the other displays.
