15 صفحه اولAutomatic Correction of Lens Distortion by Using Digital Image Processing
Many inexpensive camera lenses, especially zoom lenses, suffer from very clear distortion. We show that even with such a lens near perfect images can be obtained by using a correction algorithm based on a simple mathematical model and without any special measuring tools. See Figures 9–12 for reallife examples. The most typical cases of distortion, barrel and pincushion distortion, are illustrat...
متن کاملAutomatic Lens Distortion Correction Using One-Parameter Division Models
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 th...
متن کاملNonparametric Correction of Distortion 1 Nonparametric Correction of Distortion 1
Previous work on camera calibration, and particularly work on self-calibration, has assumed that the camera is well modeled by an ideal, relatively simple, parametric model. Real camera systems, however, diverge signiicantly from a simple pinhole perspective imaging model. Therefore, parametric calibration models are typically extended to include parameters which model distortions from perspect...
متن کاملNonparametric correction of distortion
Daniel E. Stevenson and Margaret M. Fleck Department of Computer Science, University of Iowa, Iowa City, IA 52242, USA [email protected], m [email protected] Abstract Images taken with wide-angle and inexpensive medium-angle lenses show substantial distortion, which will cause many computer vision applications to malfunction. Parametric calibration algorithms cannot handle the wide range of possi...
