How to use stereo_image_proc with different topic?

edit

Hi all,

I am a newbie in this field..

I am trying to calculate the 3d position of a specific point with respect to the camera coordinate using a stereo camera.

I'd like to use stereo_image_proc package but I am having trouble with the topic name. The warning says that the input topic is not yet advertised.

From my understanding, stereo_image_proc only recognize topics named as "stereo/left/image_raw". However, I have topic named as "left/decklink/camera/image_raw".

I tried remap option to change the topic name but it doesn't seem to work..

The below is the .launch code that I wrote..

<node name="image_listener_stereo" pkg="get_3d_pos" type="stereo_subscriber">
  </node>

  <node ns = "stereo" pkg="stereo_image_proc" type="stereo_image_proc" name="stereo_image_proc">
    <remap from="stereo/left/image_raw" to="/left/decklink/camera/image_raw"/>
    <remap from="stereo/right/image_raw" to="/right/decklink/camera/image_raw"/>
  </node>

Can anyone help me with this?
