I'm launching the nodelet with following settings.
<node name="disparity_image_proc" pkg="nodelet" type="nodelet" args="load disparity_image_proc/depth_image stereo_proc" output="screen">
<remap from="/elp/right/camera_info" to="/right/camera_info"/>
<remap from="/elp/left/camera_info" to="/left/camera_info"/>
<remap from="/elp/left/image_rect_color" to="/left/image_rect_color"/>
<remap from="/elp/disparity" to="/disparity"/>
<remap from="/depth_image" to="/depth_image"/>
The camera works and I can see the information on /camera_info and /image_rect_color topics, as well as disparity image.
Unfortunately the /depth_image topic is empty when I check it with rostopic echo command.
I've tried changing the .cpp file to set Approximate_sync to true, it didn't seem to change anything.
Do you have any ideas on what I might be doing wrong?
Thank you for your help
