提出了一种求解摄像机内参数的线性方法。首先通过空间平面上一个正方形及其对角线的图像来计算圆环点的图像，进而由圆环点对摄像机内参数的约束方程标定摄像机内参数，并给出了此约束方程具有惟一解的充要条件。该方法的特点在于无需知道正方形的任何几何信息，也不涉及图像匹配问题，而且所有计算方法均是线性的。真实图像实验结果表明，该方法具有求解精度高、鲁棒性强的优点。

In this paper , a linear approach is proposed to determine the intrinsic parameters of camera . At first, the images of the two circular points are derived from the images of square and diagonal lines in space , then some linear constraints on the intrinsic parameters are established via the obtained images of the circular points .In addition , the necessary and sufficient condition of the constraint system for a unique solution is also provided .Having obtained intrinsic parameters .The main advantages of these approaches lie in that neither the metric information of the square nor the correspondences between images are required , and the involved algorithms are all linear .The simulation and real experiment are given, and the results show that the approach has the higher accuracy and strong robustness .
