2. Camera calibration

• Internal camera parameters are orientation dependent

• Use Tsai’s 11 parameter non-coplanar camera calibration scheme technique, retaining only f, Cx, Cy for each C-arm pose

  • External camera parameters: Rx , Ry , Rz.
  • Internal camera parameters:
    • f - focal length
    • Cx, Cy - image origin
    • k radial distortion coeffficient
    • s - image scale factor
