I am trying to calibrate Asus Xtion3 using the calibration tutorial at http://wiki.ros.org/openni_launch/Tutorials/IntrinsicCalibration. For the IR calibration, I could not find rostopic /camera/ir/image_raw and proceeded to complete the steps using /camera/ir/image. The calibration seems to work successfully. So, I wanted to confirm if either of these two topics be used equivalently or will this cause an error later?
