LIBCBDETECT: Corner and Checkerboard Detection

This page contains MATLAB code for fully automatic sub-pixel checkerboard / chessboard pattern detection from our paper "A Toolbox for Automatic Calibration of Range and Camera Sensors using a single Shot". The algorithm autmatically extracts corners to sub-pixel accuracy and combines them to (rectangular) checkerboards / chessboard-like patterns. It works on a variety of imagery (pinhole cameras, fisheye cameras, omnidirectional cameras). The online calibration toolbox (which also includes the optimization algorithms for calibration) can be reached here.
