Research on Rectification of Camera’s Optical Axis Based on Vision Feedback

  • 摘要: 提出了基于视觉伺服的相机光轴反馈校正法,将图像的线性畸变与非线性畸变相分离,先采用多幅模板图像对相机进行高精度标定,获得相机非线性系数;根据这些系数经反复迭代后消除非线形畸变;再利用线性畸变,引入反馈环节精细调节相机至精确位置。该方法不需要特殊的导引装置,很好地解决了相机光轴的高精度校正问题。
    Abstract: A new method to rectify the optical axis based on visual servoing is given in this paper. This method separates the linear distortion from the non-linear distortion. Firstly, the non-linear distortion is removed through iterations on the basis of the non-linear distortion coefficients obtained by accurately calibrating camera with many pattern images. Then the position of the camera is finely adjusted by a way of feedback elements according to the linear distortion without special guiding equipment. With the help of this method, finally the problem of rectification of optical axis is perfectly solved.
