  • SYSTEMS AND METHODS FOR OPTICAL IMAGE GEOMETRIC MODELING
    Publication number: 20220084224
    Abstract: Refining a rational functional model (RFM) by subdividing the multiple images into multiple groups of sub-images according to the imaging sensor, then performing the RFM refinement for each group separately and estimating a 3D transformation using the sub-images from the central sensor as a reference.

  • 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.

  • DISTORTION CALIBRATION FOR OPTICAL SENSORS
    Publication number: 20100232638
    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.
