roslaunch openni_camera openni_node.launch on multiple client

edit

Have you tried :

• naming the différents nodes ?
• giving the topics differents names ?

Here is an example of what I do, with two kinects, on the same computer :

Parameters :

<arg name="camera1_id" default="#1" />
<arg name="camera2_id" default="#2" />
<arg name="depth_registration" default="true" />
<arg name="camera1_name" default="kinect1" />
<arg name="camera2_name" default="kinect2" />

Launching :

 <!-- Launching first kinect-->
<include file="$(find openni_launch)/launch/openni.launch">
    <arg name="device_id" value="$(arg camera1_id)" />
    <arg name="camera" value="$(arg camera1_name)" />
    <arg name="depth_registration" value="$(arg depth_registration)" />
 </include>

<include file="$(find openni_launch)/launch/openni.launch"> <arg name="device_id" value="$(arg camera2_id)"/> <arg name="camera" value="$(arg camera2_name)"/> <arg name="depth_registration" value="$(arg depth_registration)"/> </include>

By doing so, all the topics will appear in the namespace kinect1 and kinect2, for example topics : "kinect1/rgb/image_color", "kinect2/depth/image_raw", etc...

Have a nice day,

Bests regards,
