We have to deal with two major problems: on the one hand, wide-angle lenses produce a strong distortion, which makes the detection of distorted lines a particularly difficult task. On the other hand, the usual single parameter polynomial lens distortion models is not able to manage such a strong distortion. We propose an extension of the Hough transform by adding a distortion parameter to detect the distorted lines, and division lens distortion models to manage wide-angle lens distortion. We present some experiments on synthetic and real images to show the ability of the proposed approach to automatically correct this type of distortion. A comparison with a state-of-the-art method is also included to show the benefits of our method. | URI: | http://hdl.handle.net/10553/45746 | ISBN: | 978-3-642-41821-1 | ISSN: | 0302-9743 | DOI: | 10.1007/978-3-642-41822-8_52 | Source: | Ruiz-Shulcloper J., Sanniti di Baja G.
