| 摘 要： | 针对摄像头参数未知的情况,推导出基于单目视觉的球体中心在三维空间中坐标的计算公式,使用了像素间距表示的焦距这一概念,从而在推导出的公式中避免了未知参数--摄像头焦距的出现,实验结果表明该方法具有较好的稳定性和较高的精确度.

| Abstract: | As for the unknown camera parameters,the formula is derived for calculating the coordinates of the spherical center in three-dimensional space based on monocular vision.The concept of focal length is used to a pixel pitch measure,so the formula is derived to avoid the emergence of the unknown parameters-camera focal length.The experimental results show that the method has better stability and a certain degree of accuracy. |
