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.
