摘要: A method includes determining a first blend map for a first projector, the first blend map including a first plurality of attenuation factors corresponding to a region of overlap between first and second images projected by the first projector and a second projector, respectively, on a display surface, applying the first blend map to a white level measurement map that includes a plurality of white level measurement values measured from a first plurality of captured images, applying a smoothing function to the white level measurement map to generate a white level target map, and determining a scale map for the first projector from the white level measurement map and the white level target map.

摘要: A method for calibrating a camera including determining a model for associating a point of an image scene to a point of an imaging surface of the camera. The calibration method further includes determining a set of initial estimates for a set of parameters of the model and then refining the parameters in response to a set of image data of the image scene acquired by the camera.
