【摘要】 该文实现了一种自动求解摄像机内外参数的方法。首次介绍如何通过连通域标记自动提取特征点的位置,确定摄像机的主点坐标和纵横比,然后在利用Tsai方法的基础上,用径向排列约束求解大部分的外参数,再引入新的畸变模型求解其余参数。文中采用共面点标定物,不需要摄像机做任何运动就可以实现全过程的线性标定,实验验证了该法的有效性。更多还原

【Abstract】 An automatic approach for camera parameter calibration is realized.Firstly,it is introduced how to automatically get the coordinate of point through the method of region identification and calibration the aspect ratio and principal point;then solve the most extrinsic-parameters through Radial-Array-Constraints based on the method of Tsai,and finally compute the other parameters by the introducing a new distortion model.It only requires a coplanar target without camera′s motion.It is validity that experimental results show.更多还原
