Abstract:
1. A method performed by a display system, the method comprising: providing, to a first projector, an input of a first infrared pattern combined with a first portion of visual content; projecting, with the first projector, the first portion of the visual content onto a display surface for viewing by a human observer; projecting, with the first projector, the first infrared pattern from a first projection plane of the first projector onto the display surface during the projection of the first portion of the visual content by the first projector; capturing the first infrared pattern from the display surface in a capture plane of at least one image capture device having an infrared filter configured to transmit the first infrared pattern and block the visual content; and determining a first correspondence mapping between the first projector and the image capture device from at least the first infrared pattern in the first projection plane and the first infrared pattern in the capture plane.
