Abstract: Defining a display region for a projector display. An image of a camera's view of a display region is accessed. The image is displayed on a graphical user interface. The image has a first set of coordinates. The image and a reference canvas that is displayed on said graphical user interface is integrated. The integration comprises overlaying a portion of the reference canvas on the image. The reference canvas has a second set of coordinates. One of the first set of coordinates and the second set of coordinates represents a mesh of movable control points being movable from a first location to a second location on the graphical user interface. The first set of coordinates are mapped to the second set of coordinates, thereby generating a pointwise correspondence mapping between coordinate points of the reference canvas and coordinate points of the image.

Abstract: A reference set of image features is determined from an electronic data file specifying a reference image in a reference coordinate space. Rendering information describing a physical rendering of the reference image is ascertained. Calibration-enabling data is derived from the reference set of the image features and the ascertained rendering information. The calibration-enabling data is provided to calibrate an imaging system. The calibration-enabling data may be stored. The imaging system may capture an image of the physical rendering of the reference image in relation to a capture coordinate space. An extracted set of image features may be extracted from the captured image. Respective ones of the image features in the reference and extracted sets may be matched. The imaging system may be calibrated based on matched ones of the image features and the rendering information.
