| 摘 要： | 利用正方形模板的两组相互正交方向的消失点,本文提出了一种新的摄像机自标定方法.根据射影几何中的交比关系以及调和共轭性质,该方法只需拍摄三个不同方向的正方形模板图像来计算正方形平行边与对角线方向的消失点.利用消失点与光心的连线平行于该组平行直线的特性.摄像机所有的内部参数便可以线性地求解出来.实验结果表明.新方法标定精度高而可靠.使用起来简单而方便.

| Abstract: | By using two pairs of vanishing points of orthogonal directions on a square template, a new approach for camera self-calibration is presented in the paper. Based on abilities of cross ratio and harmonic conjugate in projective geometry, the proposed method is only required to spot three images from different direction and two vanishing points of parallel and orthogonal directions on the square are then calculated. By using the feature of parallel lines between vanishing points and optical center, all the in... |
