Octomap not generated

[Santosh T]

Hi every one, 

I am kinda new to 3d mapping and started using the octomapping_server package.

I am using a urdf with kinect plugin and trying to generate an octomap of the gazebo world.

When I make the necessary changes and run the  launch file, the following warning is being generated and no map is generated.

I am attaching my launch file .

Warnings:

[ WARN] [1604224040.682252307, 670.359000000]: Nothing to publish, octree is empty

 and other warnings relating to message filter

Launch file:

<launch>

<node pkg="octomap_server" type="octomap_server_node" name="octomap_server" output="screen">

<param name="resolution" value="0.1" />

<!-- fixed map frame (set to 'map' if SLAM or localization running!) -->

<param name="frame_id" type="string" value="odom" />

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

<!-- maximum range to integrate (speedup!) -->

<param name="sensor_model/max_range" value="50" />

<param name="pointcloud_max_z" value="0" />

    <param name="pointcloud_min_z" value="100" />

<!-- data source to integrate (PointCloud2) -->

<remap from="cloud_in" to="/kinect/depth/points" />

                

             

</node>

</launch>

Please help me figure this out.

Thankx

Santosh
