REAL-TIME WIDE-ANGLE IMAGE CORRECTION SYSTEM AND METHOD FOR COMPUTER IMAGE VIEWING

摘要

PROBLEM TO BE SOLVED: To alleviate distortion and perception problems in an image captured by a wide-angle camera.

SOLUTION: In general, a real-time wide-angle image correction method generates a warp table from pixel coordinates of a wide-angle image and applies the warp table to the wide-angle image to create a corrected wide-angle image. The corrections are performed with a parametric class of warping functions that include spatially varying uniform (SVU) scaling functions. The SVU scaling functions and scaling factors are used to perform vertical scaling and horizontal scaling on the wide-angle image pixel coordinates. A horizontal distortion correction is performed with the SVU scaling functions and at least two different scaling factors. This processing generates the warp table that can be applied to the wide-angle image to yield the corrected wide-angle image.
