| 摘 要： | 本文利用投影和透视变换理论以及矩阵转换知识建立了摄像机数学模型，模型中全面考虑了镜头的径向畸变和切向畸变。提出仅用中心附近点求取像面中心的简单方法。在标定模型中考虑到二维孔靶与一维工作台运动方向不垂直因素的影响，从而简化摄像机标定的操作过程，提高了标定精度。

| Abstract: | The mathematical model of camera is established by using the projective and perspective theroy and the matrix transformation theroy,which include both radial distortion and tangential distirtion. A simple method is proposed to determine the image center of camera just by using the points near the image center. The effect of non-verticality between the target plate and the 1-D stage is taken into account to simplify the calibrating operation and to improve the accuracy. |
