Zusammenfassung:IMAGE PROCESSING FOR TURBULENCE COMPENSATION A system and method of processing image data. The method comprises receiving image data for a portion of an image, the received image data capturing an object through a wave deforming medium and determining a defocus wavefront deviation using disparity in the image data (730). The method also comprises determining a strength of phase fluctuations caused by the wave deforming medium using the defocus wavefront deviation, lens intrinsic characteristics and a defocus Zernike coefficient (740); and processing the image data using the determined strength of phase fluctuations to compensate for phase fluctuations caused by the wave deforming medium (750). :Start 700 Camera calibration Capture DAF left right image pair Estimate a warp 730 map between the left and right For each images video frame 740 Determine Fried parameter rO Apply rO in turbulence compensation End Fig. 7
