| 摘 要： | 在Tsai两步法的基础上提出了一种更加稳定精确的摄像机标定方法。由于Tsai两步法中只考虑了摄像机镜头的径向畸变因素，所以为了提高摄像机的标定精度，在其基础上考虑了镜头的切向畸变情况。在求解摄像机参数的过程中，第一步同Tsai两步法采用最小二乘法求解线性方程得到外部参数，再利用最小二乘法求解关于畸变参数K1，K2，K3，K4的线性方程组，最终求得摄像机的内外所有参数。通过实验对该方法进行了验证。

| Abstract: | The article puts forward a more stable and accurate camera calibration method based on the Tsai two-stage method.In order to improve the precision of camera calibration,the tangential distortion of the lens is also considered besides the camera lens radial distortion involved in the Tsai two-stage method.In the process of solving the camera parameters,the first step gets the external parameters using the least square method as the same as the Tsai two-stage method,and then solves the linear equations on the distortion parameters K1,K2,K3,K4 using the least square method.The new method is proved by the experiment. |
