Algorithm for chessboard corner detection based on USAN
Xia Li-bing · Computer Engineering and Applications Journal · 2009
A new algorithm for chessboard corner detection based on USAN is proposed according to sysmmetrical geometry structure of USAN area and apply it to the chessboard images on real photos.The theory of algorithm is simple and it not only can detect corner quickly,but also has the revolving transformation invariability.The result shows that it can quickly detect internal corner from real photos shot by every interior angle and practicability is strong.
