So, I run roslaunch astra_launch astra.launch and use Rviz to test out my Orbbec Astra camera. The problem is that the launch application gives me these messages if I try to subscribe to a topic on Rviz:

[ WARN] [1498238437.855693874]: Camera calibration file /home/tbot1/.ros/camera_info/rgb_Astra_Orbbec.yaml not found. 
[ WARN] [1498238564.009640794]: Camera calibration file /home/tbot1/.ros/camera_info/depth_Astra_Orbbec.yaml not found.

I've looked around and I can't seem to find any configuration files similar to what it's asking for. Can anybody help me? Thanks.

These are not files that are part of the source or binary distribution, as they are unique to each camera: they contain calibration values for the intrinsics of your sensor.

To generate them, you'll have to calibrate the camera. See wiki/openni_launch/Intrinsic calibration of the Kinect cameras for a tutorial (it doesn't completely apply though, according to this post on the ORBBEC forum).

Thank you! We're trying to calibrate it now!
