A wide field of view line-scan remote sensing system includes an array of orthogonal transfer charge-coupled devices (OTCCDs) configured to record image data of an optical image of a moving object received from a lens. Further, the system includes a processor coupled to the array of OTCCDS, in which the processor is configured to scan the optical image across the array of OTCCDs; and shift pixel charges along a first axis and a second axis that substantially matches an actual image motion of the moving object while the optical image is being scanned in order to reduce an amount of image distortion across the array of OTCCDs.

Abstract: Systems and methods are described that facilitate compensating for slow scan direction displacement (e.g., skew and/or bow) defects in a raster line using slow-scan electronic registration. Input image data is buffered at low-resolution (e.g., 600 spi or the like). Displacement compensation is performed as the low-resolution contone image data is converted to high-resolution (e.g., 2400 spi or the like), and a displaced (e.g., staggered) halftoning threshold array is indexed to account for detected displacement. Displacement compensation is again performed during conversion of the high-resolution contone image data to high-resolution binary image data that is used to generate an output image.

Abstract: Due to an accumulated error from the pair-wise registration, the stitched image may be blurred or have a gap when a loop is encountered. In order to remove the accumulated error, we identify a closed loop where a first image frame overlaps with a second image frame, the second image frame being captured earlier in a scanning sequence than the first image frame; register the first image frame with the second image frame; and apply a global optimization to adjust registration parameters for the plurality of pair-wise registrations of image frames within the closed loop using global constraints.
