A system determines correspondence between locations on a display surface and pixels in an output image of a projector. The display surface can have an arbitrary shape and pose. Locations with know coordinates are identified on the display surface. Each location is optically coupled to a photo sensor by an optical fiber installed in a throughhole in the surface. Known calibration patterns are projected, while sensing directly an intensity of light at each location for each calibration pattern. The intensities are used to determine correspondences between the of locations and pixels in an output image of the projector so that projected images can warped to conform to the display surface.
A method for determining correspondence between locations on a display surface having an arbitrary shape and pixels in an output image of a projector, comprising:
The method of clam 15, in which the display surface and the projector are moving with respect to each other while determining the correspondences, warping the sequence of images, and projecting the warped sequence of input images.
A system for determining correspondence between locations on a display surface having an arbitrary shape and pixels in an output image of a projector, comprising:
The system of claim 24, in which each location is optically coupled to a discrete photo sensor by an optical fiber.
A method for determining correspondence between locations on a display surface having an arbitrary shape and pixels in an output image of a projector, comprising:
