| 摘 要： | 针对传统摄像机标定方法,在张正友平面模板两步法的基础上,提出了一种简便的双立体摄像机标定方法, 在标定中通过选取图像中心附近的点作为初始预测值,再进行非线性搜索来确定摄像机内外参数由于该方法在摄像机畸变模型中充分考虑了切向畸变的影响,使得标定应用范围更广.实验证明,标定模扳制作简单,标定过程快捷具有较高的精度,完全可以满足双日立体视觉应用的要求.

| Abstract: | Aiming at the classic stereo camera calibration approach,a simple and convenient binocular stereo camera calibration approach is brought forward based on Zhang's two-stage approach in this paper,and the author of this paper chooses the points near the center of images as the initial guess,then evaluates the intrinsic parameters and extrinsic parameters of camera by nonlinear search.Taking the effect of tangential distortion into account,this method has much wider application in camera calibration.The experi... |
