I tried to launch the laser_scan_matcher package node. This is my launch file, but I can not see nothing on my rviz tool. Is something wrong with my launch file or just a rviz configuration? The launch file is like this


<param name="/use_sim_time" value="true"/>

<node name="rosplay" pkg="rosbag" type="play" args="/home/Daniel/Desktop/Data/test-41.bag           --clock"/>

<node pkg="tf" type="static_transform_publisher" name="baselink_laser" args="0 0 0 0 0 0 /base_link /laser 10"/>
<node pkg="tf" type="static_transform_publisher" name="laser_imu" args="0 0 0 0 0 0 /laser /base_imu 10"/>
<node pkg="tf" type="static_transform_publisher" name="baselink_camera" args="0 0 0 0 0 0 /base_link /camera 10"/>

<node pkg="laser_scan_matcher" type="laser_scan_matcher_node" 
    name="laser_scan_matcher_node" output="screen">
    <param name="use_alpha_beta" value="true"/>
    <param name="max_iterations" value="10"/>

<!-- Start an rviz node with a custom configuration for the viewpoint, map_server, trajectory, laser scans, etc -->
<node pkg="rviz" type="rviz" output="screen" name="rviz" args="-d $(find pow_analyzer)/launch/pow_rviz.vcg"/>

The bag file is 150 sec long. So have to add this loop <node name="rosplay" pkg="rosbag" type="play" args="/home/Daniel/Desktop/Data/test-41.bag --loop --clock"/>. Wright? And the Rviz settings?I mean the target and fixed frame?

rosbag is only going to play the data once. How long is that file?

If you want to play back the file repeatedly, add --loop to the rosbag arguments.
