An Improved Method for Wild-Angle Image Correction

Abstract:

Images taken by wide-angle cameras tend to have severe distortions which pull points towards the optical center. Matlab calibration toolbox is widely used in computer vision for its simplicity and strong interactivity; however it cannot accurately extract corners from wide-angle image, and be unable to correct image automatically. This paper proposes an improved wide-angle image correction method which can obtain corners precisely and implement correction automatically. The experimental results demonstrate this method not only improves the accuracy of corner extracting, but also makes the wide-angle image correction automated.
