基于共面圆的双目立体视觉分步标定法

计算机视觉中,在对景物进行定量分析或对物体进行精确定位时,都需要进行摄像机标定,即准确确定摄像机的内外参数.为了快速、有效地进行摄像机的标定,针对常用的带有一阶径向畸变的小孔摄像机模型,提出了一种简单有效的分步标定方法.先用预标定法得到左右摄像机主点坐标参数,然后再用TSAI两步法获得左右摄像机的内外参数,最后以左摄像机光心为世界坐标系原点,通过坐标转换关系,进而得到双目视觉的各种标定参数.该方法实验要求低,不需要移动摄像机.通过实验,验证了该方法能够准确、有效地求出各标定参数.

Binocular stereo vision step by step calibration based on coplanar circle

Camera calibration is one of the basic tasks for analyzing the geometry of a scene and determining the shapes and locations of objects in vision. It is important to calculate the internal and external parameters of a camera used when viewing. In order to calibrate camera quickly and efficiently,a simple and effective setp-by-step method of calibration was proposed using a radial-order aberration small camera model. First pre-demarcation was used to get the main point coordinates,and then the internal and ex...
