EasyCamCalib is a complete matlab toolbox for calibrating a camera using a single image of a planar checkerboard patter. It is specifically meant for cameras with lenses presenting moderate to high radial distortion and DOES NOT WORK if the distortion is not noticeable.
The algorithm requires minimum user intervention - no need of clicking corners - and provides a reliable calibration result from a single image. More images can be used for improving accuracy and robustness.
The toolbox is very easy to use having a nice GUI, complete documentation, and a tutorial video.
