I use ros several times,so I am not familiar with ros. My desktop install ubuntu 16.04 LTS,and Iinstall ROS Kinetic.

then I install Openni according this website https://www.reddit.com/r/ROS/comments/6qejy0/openni_kinect_installation_on_kinetic_indigo/

and I use Kinect for Xbox 360 (2010) for my 3d sensor.

when I type this command on terminal : roscore

then I type this command on the another terminal :roslaunch openni_launch openni.launch

it show some warnings

[ WARN] [1531748660.382091260]: Camera calibration file /home/my/.ros/camerainfo/rgbA00365A11891035A.yaml not found.

[ WARN] [1531748660.382280286]: Using default parameters for IR camera calibration.

I check /home/my/.ros/camera_info and find the folder do not have both of this .yaml file.

Did I do something wrong or miss some steps?

Please help. I will appreciate you
