Abstract:
1. A method for calibrating a camera array, comprising: capturing a first image of an environment including an optical target using a first camera, the optical target includes a plurality of symmetrical shapes; determining a plurality of centroid locations within the first image corresponding with the plurality of symmetrical shapes; determining one or more distortion parameters associated with the first camera based on the plurality of centroid locations; generating a reduced distortion image using the first image and the one or more distortion parameters; outputting the reduced distortion image; capturing a second image of the optical target using a second camera different from the first camera; determining a registration mapping for the second image onto the reduced distortion image; generating a registered image based on the second image and the registration mapping; and outputting the registered image.
