I am using Kinect and Asus camera as 3d sensors.

The problem is that when I run

roslaunch openni_launch openni.launch

I am able to see the depth image when using rqt_image_view for the topic /camera/depth/image_raw.

However, if I run

roslaunch turtlebot_bringup 3dsensor.launch

I cannot find anymore the depth image, although I set depth_registration and depth_processing to true.

I used the following command:

include file="$(find turtlebot_bringup)/launch/3dsensor.launch">

<arg name="rgb_processing" value="true" />

<arg name="depth_registration" value="true" />

<arg name="depth_processing" value="true" />

<arg name="scan_topic" value="/scan"/>


But, still I am not able to get the depth image.

Did I miss any configuration to be able to activate depth image in 3dsensor launch file?

Thank you

can you list the topics that are available once you have run the launch file, they may be there but not in the same namespace

Actually, I get all the topics with both launch files, but the problem is that the depth_image does not have any data when I try to echo it or subscribe to it.
