Hello hudvin,
I think you should rename this: <group ns="wide_stereo"> to <group ns="your_camera_namespace"> (e.g. if /stereo/left/camera_info then <group ns="stereo">)
I have 2 webcams and custom node to synconize images.
vslam config
<launch>
<!-- Run stereo VSLAM on wide stereo data -->
<group ns="wide_stereo">
<node name="stereo_vslam_node" pkg="vslam_system"
type="stereo_vslam_node" args="$(find vocabulary_tree)/holidays.tree $(find
vocabulary_tree)/holidays.weights $(find vslam_system)/data/calonder.rtc"
output="screen" cwd="node" >
<remap from="left/image_rect" to="/sync/left_camera/image" />
<remap from="left/camera_info" to="/sync/left_camera/camera_info" />
<remap from="right/image_rect" to="/sync/right_camera/image" />
<remap from="right/camera_info" to="/sync/right_camera/camera_info" />
</node>
</group>
<!-- Show VO tracks -->
<node name="vo_tracks_view" pkg="image_view" type="image_view">
<remap from="image" to="/vslam/vo_tracks/image" />
</node>
</launch>
vslam node dies in a few seconds after start (see attached file).
vslam was install from repository (unstable)
