I do the tutorial in http://www.ros.org/wiki/openni_launch/Tutorials/IntrinsicCalibration?action=show&redirect=openni_camera%2Fcalibration

3.RGB camera

roslaunch openni_launch openni.launch

rosrun camera_calibration cameracalibrator.py image:=/camera/rgb/image_raw camera:=/camera/rgb --size 5x4 --square 0.0245

I commit my successful calibration

and

4.IR(depth)camera

rosrun camera_calibration cameracalibrator.py image:=/camera/ir/image_raw camera:=/camera/ir --size 5x4 --square 0.0245

I also commit my successful calibration

Question.

  1. How can I know the calibration result?

  2. How can I compare the before calibration?

(Should I see a noticeable difference when viewing the raw and rectified images?)

You can view the yaml file

$ ls ~/.ros/camera_info/
depth_B00362708888047B.yaml  rgb_B00362708888047B.yaml

Perhaps it is possible seen that you have less distortion round the edges of your image?
