摘要
提出一种利用立方体上点在双目摄像机上不同成像的几何约束关系进行标定的方法。即在传统标定方法的基础上,通过1个3个面贴有棋盘格的不规则立体标定件上对应点在两个摄像机上位置关系对获取的摄像机内外参进行修正,从而实现较为便捷地获取矩阵的内外参信息。实验表明,该算法能够准确地获取双目摄像机的内外参数据,并将误差控制在0.1%以下。
A method for calibrating the geometric constraints of different imaging on a binocular camera using a point on the cube is proposed.That is to say,on the basis of the traditional calibration method,the acquired internal and external parameters of the camera are corrected by the positional relationship between the corresponding points on the two cameras with the three points on the three-dimensional irregular calibration plate,so that the matrix can be obtained more conveniently.Internal and external parameters.Experiments show that the algorithm can accurately obtain the internal and external parameters of the binocular camera and control the error to 0.1%.
