畸变普遍存在于光电系统中，影响光电系统的成像。为了解决这个问题，研究Tsai模型，实现Tsai算法的标定，并利用线性变换方法或者透视变换矩阵求解摄像机参数，再用之前得到的结果带入非线性方程，解得一个估计值，然后用估计值作为初始值，根据特定的算法来迭代，直达满足条件为止，求解其他参数。并评估算法的精度。%Distortion widely exists in optical system, it affects optical system imaging. In order to solve this problem, TASI model are studied to achieve calibration of Tsai algorithm, and the method of linear transformation or perspective transformation matrix is used to solve the camera intrinsic parameters. And then, the results obtained before are subsitituted into non linear equation to get an estimate value and take the estimate value as initial value to carry out the iteration by the specific algorithm until meet the conditions and then solve other parameters and evaluate the algorithm's accuracy.
