摄像机标定是计算机视觉的关键技术之一.针对现有的标定技术计算过程复杂,标定物使用不方便等问题,提出了一种用于双目摄像机自标定的方法,该方法要求场景中有两组正交的平行直线即可进行标定,利用其在图像平面上形成的消失点之间的约束关系来建立标定方程,从而求解出摄像机的内外参数,再结合双目立体视觉原理标定双目摄像机的结构参数.将该方法在实验室现有设备上进行对比实验.实验结果表明,该方法简单、有效,可广泛应用于机器视觉研究、三维重建等多个领域.

Camera calibration is one of the key technologies to computer vision. According to problems from presently calibration technology such as complicated calculation process and inconvenient calibration tar?gets usage, a self-calibration method for binocular cameras is proposed. Calibration process can be performed when there are two groups of orthogonal parallel line in scene. A calibration equation is built according to con?straint relations among vanishing points forming in the image planes. So the intrinsic and extrinsic parameters of cameras are calculated. And structure parameters of a binocular camera are calibrated incorporating with the prin?ciple of binocular stereo vision. Comparison experiments are performed to presently laboratory equipments by the method. Experimental results show that the method is easy, effective and can be used in many fields such as research on machine vision and 3D reconstruction.
