| 摘要: |
| 利用3个正交方向的消影点在图像平面上提供的几何关系，首先计算出主点坐标，然后根据正交方向上的消影点与消影线对绝对二次曲线的像的约束方程，计算出其余参数；方法原理简单，只需要一幅图像就可实现摄像机内参数的求解；结果表明，方法具有较高的精度和较好的稳定性。 |

| Abstract: |
| Making use of the geometry relation of three orthogonal vanishing points, first the coordinates of principal point is computed. According to the constraint equation of the image of absolute conic provided by the vanishing point and vanishing line in orthogonal directions, the remaining parameters are calculated. The method is easy to use and only one image can calculate the camera intrinsic parameters. The experiment results show that this approach is effective and precise. |
