A New Algorithm for Automatically Detecting Chessboard Corners
Xiaowei Hou · Jisuanji gongcheng · 2004
A new algorithm for automatically extracting chessboard corners is presented. In this paper, the coarse-to-fine scheme is adopted and all the necessary corners can be obtained quickly and accurately through integration of Radon transform, Harris corner detector and Forstner detector. The algorithm has two traits relative to the traditional approach: the position of the corners can be determined automatically while not requiring manual interposition, and high precision could be acquired and the mean position error is below 0.1 pixels.
