Calibrating a seamless tiled display image having multiple overlapping
discrete images produced by multiple displays includes generating a
display-to-screen spatial transformation function to reduce one or more
undesirable geometric projector characteristics for each of the projectors
used in the tiled display. Then the method includes generating a
screen-to-camera spatial transformation function to reduce one or more
undesirable geometric camera characteristics for each of the cameras used
in capturing the tiled display images used in the calibration. Then the
method requires generating a spatial luminance transformation function for
effective color calibration for each of the display images in the tiled
display. Then the method requires inputting a high-resolution image into a
tiled display processor to form the tiled images of the tiled display,
segmenting the inputted high-resolution image to form tiled images based
on an array of images used in the tiled display, and pre-warping each of
the segmented tiled images using the display-to-screen spatial
transformation function to reduce the one or more non desirable geometric
projector characteristics. Then the method requires applying an inverse of
the spatial-luminance transformation function to each of the pre-warped
images to effectively blend colors in the tiled display images.
