【摘要】 针对摄像机标定中广泛使用的棋盘图像,提出了一种新的角点检测算法,并利用棋盘角点的数学特征,设计了边链-中心二重判定条件.该算法易于实现、计算量小,对旋转变换、亮度变换、变形等具有较好的鲁棒性,并对边缘模糊有良好的适应性,可在线连续提取多幅图像的角点,适用于摄像机在线自动标定.更多还原

【Abstract】 Aiming to the checker board corner patterns which are most widely used in camera calibration,a new algorithm is proposed.On the basis of considering the mathematical characters of the corners,edge-center dual criterion is designed.The algorithm can be executed easily.It is robust for the rotation transform,the intensity transform and the distortion.It also adapts to the edge blur.With this method,it is easy to deal with many images continually,so it is useful in camera automatic calibrating online.更多还原
