rviz not showing data

[jsalfity]

Hi, I'm not seeing the data in rviz. I'm referencing the instructions from step 6 of the wiki.

Rviz is not showing anything but the grid and I think I know why, but would like some reassurance and guidance if possible. Here's what I see in rviz after setting Fixed Frame to camera_link, PointCloud2 to /localization/point_cloud and MarkerArray to localization/visualization_all_handles

I would expect to see at least the point cloud data if localization did not recognize any handles

I'm launching an Xbox camera with roslaunch freenect_launch freenect.launch. At this point I don't have an actual robot running so I don't have anything else but the camera_link as a coordinate frame.

My output from rosrun rqt_tf_tree rqt_tf_tree (to view the /tf tree) looks like this:

My output from rqt_graph looks like this:

So... I think I know why there is no output in rviz, its because there is no link between /tf and /localization.

Can anybody drop any hints if I'm on the right track, if there are solutions out there or if I'm just plain way off.

Thanks!

Can you see the point cloud if you look at the camera's point cloud topic, e.g., /camera/depth_registered/points (if this topic exists in your case)?

With respect to the handles/grasps, is there any terminal output that indicates that grasps/handles have been found?

@atenpas Yes, there are definitely images coming through the /camera/depth_registered/points topic when I use PointCloud2 in rviz. They are the point cloud images that I would expect.

When I try $ rostopic echo /localization/handle_list I get the message: ERROR: cannot load message class for [handle_detector/HandleListMsg]. Are your messages built?

Even if handles haven't been found, I would still think I would be able to see the output from /localization/point_cloud. Did my hunch of the /localization not being connected to /tf raise any suspicion?

Thanks for the help!

Realized I wasn't subscribing to the topic /camera/depth_registered/points correctly Worked.
