Distortion Correction Modeling Method for Zoom Lens Cameras with Bundle Adjustment

Mechanically assisted liquid lens zoom system for mobile phone cameras

Camera systems with small form factor are an integral part of today’s mobile phones which recently feature auto focus functionality. Ready to market solutions without moving parts have been developed by using the electrowetting technology. Besides virtually no deterioration, easy control electronics and simple and therefore cost-effective fabrication, this type of liquid lenses enables extremel...

A Hough transform-based method for radial lens distortion correction

The paper presents an approach for a robust (semi-)automatic correction of radial lens distortion in images and videos. This method, based on Hough Transform, has the characteristic to be applicable also on videos from unknown cameras that, consequently, can not be a priori calibrated. We approximated the lens distortion by considering only the lower-order term of the radial distortion. Thus, t...

Self calibration of stereo cameras with lens distortion

In this paper we present a new method for the self calibration of a stereo camera pair including lens distortion. A single stereo image pair is used without calibration object or prior knowledge of the scene. The method is based on the estimation of a stereo image correspondence field followed by extraction of the calibration parameters. The correspondence field is obtained by a Markov Random F...

Lens Distortion Correction Method of Linear Array Camera

The imaging technology basing on binocular stereo vision of linear array camera can effectively detect foreign bodies existing in automobile chassis so that ensure the safety of people. However, the distortion of camera lens can influence the precision of system measurement and three-dimensional reconstruction. Because of the difference between the imaging principle of linear array camera and t...
