Radial distortion, also known as the fish-eye effect, is one of the main categories of camera distortions. It distorts the image, creating a hemispherical (panoramic) effect. The effect on facial ...

It shows how to correct lens distortions in images using OpenCV, based on chessboard calibration images taken with the same camera. In my case, my mobile phone camera introduces a radial distortion ...

To model radial distortion there are two main approaches; either the image points are undistorted such that they correspond to pinhole projections, or the pinhole projections are distorted such that ...

Structure from motion (SfM) and self-calibration from images of unknown radial distortions could fail under some critical configurations and produce distorted reconstruction results. In this paper, we ...
