一种基于三消隐点的摄像机自标定算法

提出了一种对摄像机进行自标定的方法.该方法是利用自然场景中三组两两正交的平行线所获得的消隐点之间具备的约束条件来实现标定的,并能够对获取的消隐点进行优化校正.利用该方法开展了实验研究,并与采用传统标定方法得到的结果进行了比较,结果表明本文所提出的算法具有较好的应用前景.

An Algorithm of Self-Calibration Based on Three Vanishing Points

In this paper, a self-calibration technique of the camera based on three vanishing points is introduced. This calibrating method is realized by the constrained condition among the vanishing points obtained by using three groups of in pairs orthogonal parallel lines in the nature scene. The optimization correction of the obtained vanishing points can be obtained. The experimental research has been done and the result has been compared with the traditional method. The result shows that the algorithm proposed in this paper has better application prospeet.
