  • Distortion calibration for optical sensors
    Patent number: 8452123
    Abstract: A method for calibrating an imaging instrument, possibly located on an aircraft or satellite, is described. According to the method, an image acquired by the instrument is ortho-rectified, and then co-registered and correlated with a reference image. In this way, ground disparities between the acquired image and the reference image are measured. Updated instrument pointing directions that correct for the disparities measured are then determined and adopted as corrective calibrations for the distortions of the instrument.
    Type: Grant
    Filed: December 20, 2008
    Date of Patent: May 28, 2013
    Assignee: California Institute of Technology
    Inventors: Sebastien Leprince, Pablo Muse', Jean-Philippe Avouau
  • Ortho-rectification, coregistration, and subpixel correlation of optical satellite and aerial images
    Patent number: 8121433
    Abstract: Methods for mapping and resampling images such as satellite or aerial images are presented, including methods to measure relative displacements of images, methods to refine look directions of an aircraft or satellite for aerial or satellite imaging and methods to ortho-rectify and co-register raw satellite or aerial images.
