Hi,

I'm trying to calibrate the Kinect depth camera to the built-in RGB camera. I calibrate the intrinsic parameters without any problem but I have a problem with the IR image:
running rosrun image_view image_view image:=/camera/ir/image_raw I just see a black image, while during the calibration with rosrun camera_calibration cameracalibrator.py image:=/camera/ir/image_raw camera:=/camera/rgb --size 5x4 --square 0.0245 the IR image was displayed correctly.

For this reason I cannot compute the extrinsic parameters between the RGB and the IR camera using camera_pose_calibration node...

With rqt_gui I can see this:

while running the camera_pose_calibration (the rgb images are coming from a bag file):

I am using Ubuntu 14.04 and ROS Indigo. I had to install the older version of driver manually:
( libopenni-sensor-primesense-dev and libopenni-sensor-primesense0). I can see from rqt_graph that both node are subscribing to the same topic...

Any ideas?

Thank you!

Did you solve this problem already? I met the same error as you mentioned.
