The present invention includes a real-time wide-angle image correction
system and a method for alleviating distortion and perception problems in
images captured by wide-angle cameras. In general, the real-time
wide-angle image correction method generates 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 using 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 using the SVU scaling
functions at and at least two different scaling factors. This processing
generates a warp table that can be applied to the wide-angle image to
yield the corrected wide-angle image.
