rgbdslam hydro no display

edit

I still only get an empy window as shown in the picture at the top of this thread... pressing enter to start doesn't change things.

In the terminal that runs $roslaunch openni_launch openni.launch

I see a lot of messages TF2 exception Invalid argument "/camera_rgb_optical_frame" passed ...

Full single message block:

Invalid argument "/camera_rgb_optical_frame" passed to lookupTransform argument target_frame in tf2 frame_ids cannot start with a '/' like:

This is on 14.04.1 LTS using ROS Indigo.

I fixed that by updating the openni launch file and adding a prefix. Then I got images in the rgbdslam GUI!

I also have the same messages. @monkeyiq, can you give me more details on how to fix this one by adding a prefix?

yooncs8, you need to remove "$(arg tf_prefix)/" from the rgb_frame_id and depth_frame_id parameters in openni.launch.

hi i had the same problem rgbdslam does not displayimage, i worked with hudro version, ubunto 12.04 and i still have the problem until now, please is there anyone who can help me?

@celston I already have updated file but it still giving the same error, e.g., <arg name="camera" default="camera"/> <arg name="rgb_frame_id" default="$(arg camera)_rgb_optical_frame"/> <arg name="depth_frame_id" default="$(arg camera)_depth_optical_frame"/> Any idea?
