how to use CV_CALIB_USE_INTRINSIC_GUESS in calibrateCamera

Hi,

I am confused about how and when I can use the CV_CALIB_USE_INTRINSIC_GUESS in the calibrateCamera function.

The documentation says: "Currently, initialization of intrinsic parameters (when CV_CALIB_USE_INTRINSIC_GUESS is not set) is only implemented for planar calibration patterns (where Z-coordinates of the object points must be all zeros)."

  1. Does this mean: if the calibration patterns are planar, I can set an initial guess myself of the contrary?
  2. I have a 3d calibration pattern, but don't have a cameraMatrix, what is the correct configuration when using the function?

Thanks.
