Yes...
Internal camera parameters:
Ncx: [sel] Number of sensor elements in camera's x direction
Nfx: [pix] Number of pixels in frame grabber's x direction
dx: [mm/sel] X dimension of camera's sensor element
dy: [mm/sel] Y dimension of camera's sensor element
dpx: [mm/pix] Effective X dimension of pixel in frame grabber
dpy: [mm/pix] Effective Y dimension of pixel in frame grabber
Cx: [pix] Z axis interception of camera coordinate system
Cy: [pix] Z axis interception of camera coordinate system
sx: [] Scale factor to compensate for any error in dpx
f: [mm] Focal length of camera
Kappa1: coefficient for second order (nonlinear) lens distortion
Note: sx compensates for errors in dx, dy, because we do not really know the true value ==> f may also be a little bit off...
External camera parameters:
(tx, ty, tz) Translational parameters for transformation camera -> calib.body
(rx, ry, rz) Rotational parameters for transformation camera -> calib.body
r1...r9: Redundant, again Rotational parameters (here 3x3 rotation matrix values)
Camera coordinate system lies in center of camera , z-axis = viewing direction
Calib.body coordinate system can be seen in the pattern printout
