Hello all,

I am running Ubuntu 12.04 with ROS Fuerte and the latest openi_camera and openni_launch packages that are available through Ubuntu's package manager. I have an XBox 360 Kinect. When I run roslaunch openni_launch openni.launch, I get the output below. No errors are present, but yet the green light continues to flash, the IR light never turns on, and the unit just sits there endlessly. Firing up rviz and setting fixed and target frames to /camera_depth_optical_frame does nothing.

Strangely, when I use the test programs for libfreenect, it works just fine. Any ideas?

Thanks.

Sounds like a bug in the driver. Please open a defect ticket.

EDIT: I talked with @piyushk about this yesterday. He thinks the lower-level openni library was re-released with new bugs a while back, causing the ROS driver to stop working reliably.

I'm not so sure that this is a bug. Did you try using rostopic to see if any data is coming over. When I start openni_launch, my green light flashes and the IR light stays off. Then as soon as something subscribes to an IR topic, the light turns on and stays on until there are no subscribers.

Comment by jarvisschultz on 2012-10-16:
Just opening rviz and setting it's frames is not sufficient to turn on the IR. Something like rostopic hz /camera/depth/points immediately turns it on.
