Kinect openni_launch TF2 exception warning
Hi all,
I tried to run other package with openni_launch of ASUS Xtion. In the launch file of other package, it subscribes to /camera/depth_registered/points, /camera/rgb/image_raw, /camera/depth_registered/image, and /camera/depth/camera_info. When I launched roslaunch openni_launch openni.launch, it was fine. But when I launched the other package, I got this following warning repeating over and over and could not subscribe to kinect rostopics.
[ WARN] [1412634733.035488109]: TF2 exception: Invalid argument "/camera_rgb_optical_frame" passed to lookupTransform argument target_frame in tf2 frame_ids cannot start with a '/' like:
Anyone who has seen this warning before? I am using ubuntu 14.04 and ROS indigo. I did openni-related apt-gets and installed openni_launch. The version of my ASUS Xtion is old one, so openni_launch package is comparable with it, and I was able to subscribe all of rostopics properly, which is fine. It looks like TF2 related problem, but I do not know exactly why it happened.
Thank you.
