| 摘 要： | 为了提高摄像机的标定精度和灵活性,提出了基于正交消失点对的摄像机标定方法。该方法采用了摄像机线性模型,仅需设计制作简易的标定模板并以不同的视觉角度拍摄多幅(至少3幅)平面标定模板的图像,利用消失点的性质和标定模板的几何特征,从每幅标定模板图像中可获得正交消失点对与标定矩阵之间的2个几何约束条件,从而线性标定出所有摄像机内参数,通过仿真实验和真实实验验证了该方法具有较高的标定精度和鲁棒性。

| Abstract: | A method for camera calibration based on orthogonal vanishing point pair is proposed to improve the precision and flexibility of camera calibration.The method only requires camera to shoot a simple self-designed planar calibration pattern for a few(at least three) different unknown views.According to the properties of vanishing point and the geometry feature of the planar calibration pattern,two geometry constraints can be found between orthogonal vanishing point pair and calibration matrix.And then all the five intrinsic parameters of the camera can be recovered linearly.Both computer simulation and real experiment data were used to test the proposed method.Experimental results of simulated data and real data show that the proposed method is more accurate and robust. |
