Custom, efficient optical distortion reduction system and method

摘要

Systems and methods for custom efficient optical distortion reduction where an image is pre-distorted based on the characterization of an optical system, so that when projected onto a curved optical surface the viewer sees a non distorted image. The approach involves characterizing an optical system with an optical distortion polynomial and then segmenting the field of view into smaller segments. Each segment is characterized with a lower order polynomial. The image is segmented and a computer processor applies distortion correction to each image segment based on the polynomial determined for the associated smaller segment. Alternately, two or more of the image segments may be processed simultaneously using a plurality of microprocessors. The data associated with each image segment is then stitched together to recreate a pre-distorted version of the original image.
