Claim One:
1. A method for creating input for an image warping calibration process, comprising: projecting a calibration image with a projector at a first display surface and one or more second display surfaces, the calibration image including four or more dots and three or more scale points, the locations of the dots and scale points being defined in a first coordinate space; determining a location for a registration point in the first coordinate space and adding the registration point to the calibration image; capturing the projected calibration image with an imaging device, the captured image including a captured registration point, captured scale points, and captured dots; identifying a location of the captured registration point in a second coordinate space; identifying a location of each captured scale point in the second coordinate space; identifying captured dots that are projected onto the first display surface and their locations in the second coordinate space; mapping each of the captured dots identified as being projected onto the first display surface to a corresponding dot of the calibration image; and identifying dots of the calibration image that are not projected onto the first display surface, determining locations of each of the dots identified as not being projected onto the first display surface in the second coordinate space, and adding a synthetic dot to the captured image for each dot identified as not being projected onto the first display surface.
