Abstract
We present a method to automatically correct the radial distortion
caused by wide-angle lenses using the distorted lines generated by the
projection of 3D straight lines onto the image. Lens distortion is
estimated by the division model using one parameter, which allows to
state the problem into the Hough transform scheme by adding a distortion
parameter to better extract straight lines from the image. This paper
describes an algorithm which applies this technique, providing all the
details of the design of an improved Hough transform. We perform
experiments using calibration patterns and real scenes showing a strong
distortion to illustrate the performance of the proposed method.
