Name Dependent Node?????

edit

I am trying to use visp_auto_tracker this three cameras, the simplest way I see to this is to use three nodes. This does not work because for some reason visp_auto_tracker doesn't work if the node name is not "visp_auto_tracker". Here is my launch file:

<launch> 
    <!-- you can only use the debug display if name is "visp_auto_tracker" appearently nothing works if not visp_auto_tracker-->
    <node pkg="visp_auto_tracker" type="visp_auto_tracker" name="visp_auto_tracker" output="screen">
    <param name="model_path" type="string" value="$(find visp_auto_tracker)/models" />
    <param name="model_name" type="string" value="pattern" />
    <param name="debug_display" type="bool" value="True" />

    <remap from="/visp_auto_tracker/camera_info" to="/primesense2/rgb/camera_info"/>
    <remap from="/visp_auto_tracker/image_raw" to="/primesense2/rgb/image_raw"/>      
    <!--<remap from="/visp_auto_tracker/camera_info_2" to="/primesense1/rgb/camera_info"/>
    <remap from="/visp_auto_tracker/image_raw_2" to="/primesense1/rgb/image_raw"/>
    <remap from="/visp_auto_tracker/camera_info_3" to="/primesense3/rgb/camera_info"/>
    <remap from="/visp_auto_tracker/image_raw_3" to="/primesense3/rgb/image_raw"/>-->
  </node>
    <node pkg="visp_auto_tracker" type="visp_auto_tracker" name="visp_auto_tracker_ps1" output="screen">
    <param name="model_path" type="string" value="$(find visp_auto_tracker)/models" />
    <param name="model_name" type="string" value="pattern" />
    <param name="debug_display" type="bool" value="True" />

    <remap from="/visp_auto_tracker/camera_info" to="/primesense1/rgb/camera_info"/>
    <remap from="/visp_auto_tracker/image_raw" to="/primesense1/rgb/image_raw"/>
  </node>
    <node pkg="visp_auto_tracker" type="visp_auto_tracker" name="visp_auto_tracker_ps3" output="screen">
    <param name="model_path" type="string" value="$(find visp_auto_tracker)/models" />
    <param name="model_name" type="string" value="pattern" /> 
    <param name="debug_display" type="bool" value="True" />

    <remap from="/visp_auto_tracker/camera_info" to="/primesense3/rgb/camera_info"/>
    <remap from="/visp_auto_tracker/image_raw" to="/primesense3/rgb/image_raw"/>
  </node>
</launch>

Does anyone know how I can fix this? I modified a different version of the tracker to work with three cameras, but it has stability issues.
