Hi, I am trying to record objects with a kinect using ar_bounding_box and re_object_recorder. I installed them via roboearth stack (with svn up -r2047). I'm using Ubuntu 11.10 with ROS electric.

Here is what I did:

roslaunch openni_launch openni.launch
roslaunch ar_bounding_box ar_kinect.launch 
rosrun re_object_recorder record_gui

I set the registered_depth param true in device.launch, which is included by openni.launch.

Everything seems to run fine, but the the resulting_pcl topic stays empty. http://imageshack.us/a/img221/6375/nopointcloud.png (image description) http://imageshack.us/a/img21/4997/objectpointcloud.png (image description)

The only PointCloud2 topic, that's filled, is the /camera/depth_registered/points http://imageshack.us/a/img4/6539/cameradepthregisteredpo.png (image description)

But I also can't show this Point Cloud in rviz: http://imageshack.us/a/img341/6861/rvizjpg.png (image description)
