Camera linear calibration method with coplanar points based on Tsai

提出了一种基于Tsai的共面点线性标定求解摄像机内外参数的方法。首先确定图像的纵横比和光学中心的标定。然后对Tsai算法的第二步进行改进,求解f,k,tz。该方法的特点是采用共面点标定物,利用线性标定进行求解。实验结果表明,该方法是一种精度较高的、简单实用的摄像机标定方法。

An approach with calibration with coplanar point for camera intrinsic and external parameters based on Tsai is proposed. First the freely ratio and the optical focus should be resolved. Then the f, k,tz are figured out by improving the second step of Tsai. The characteristic of the method apply linear calibration and coplanar points.The outcome demonstrates that the method has a higher accuracy and is an effective simple calibration method.
