摘要:
Camera calibration technology has been widely applied to electronic measurement engineering. According to the calibration needs manual confirmation corner time-consuming and the problem which possibly exists in setting error, this paper presents a square corner detection algorithm of black-and-white checkerboard for automatic dual-rotating template which can obtain feature points which needed for the calibration of black-and-white chessboard. The algorithm combines with black-and-white detecting operator (BW) thinking, through the construction of double operator template, regulate parameter and template for self-adaption according to the results of detection, detect corners on a black-and-white checkerboard iteratively, and achieve the forecast effect at last. The algorithm not only practical, but also enhance the detection accuracy of effective corner in checkerboard and noise inhibiting ability. © 2012 Springer-Verlag Berlin Heidelberg.
