| 摘 要： | 讨论了一种基于主动视觉的摄像机线性自标定方法,在摄像机为完全的射影模型,即畸变因子(skew factor)存在时,通过控制摄像机作一次纯轴向运动和3组两正交运动即可线性地标定出摄像机的所有5个内参数.当摄像机为四参数模型,即畸变因子为零时,只需控制摄像机作2组两正交运动即可线性标定出其4个内参数.模拟实验和真实图像的实验结果表明,该方法能够比较准确地标定出摄像机的所有内参数.

| Abstract: | A linear self-calibration technique based on orthogonal motion is brought forth.When the camera model is one that is complete perspective,the five intrinsic parameters of the camera can be calculated linearly by controlling the camera to undergo a pure axial motion and three two-orthogonal motion.When the camera's skew factor is zero,only two two-orthogonal motion is needed to calculate the camera's intrinsic parameters linearly.Simulative and real experimental results show that the intrinsic parameters can be calculated precisely by applying this technique. |
