Dear all,

Instead of using freenect_launch package, I published all depth_image_proc required images and infos by myself and successfully generated pointcloud since I can echo specified topic and it did have response. The problem right now is when I want to use pointcloud to generate actomap in moveit, I assume since I lose the tf between pointcloud and world, the message will always drop. But because I don't know what frame name of pointcloud, I don't know what I should write down when I launch tf publisher. Any idea for how to get the frame name of my pointcloud? Thanks in advance for any help.

If you're publishing the images yourself should be setting the frame_ids in your code. Or else it's a parameter on the intermediate pipeline. You can always find out the frame_id on a message by looking at the output of rostopic echo .

Got it. So the frame_id is specified in the header of message. Right now after launch tf between world and pointcloud in move_group.launch, when I run rviz, it always crashed because of failure to call service /get_planning_scene. But I did launch move_group.launch. Any idea? Thanks for reply.
