Description

Hello everyone,

I am a newbie at 3D mapping, and trying to use octomap with ZED Mini for path-planning applications with mobile robots. Utilizing ROS Noetic (Ubuntu 20), my launch file is simple: `

<!--Running an Octomap server -->
  <node pkg="octomap_server" type="octomap_server_node" name="octomap_server">
      <param name="resolution" value="0.1" />
      <!-- fixed map frame  -->
      <param name="frame_id" type="string" value="/zed/zed_node/odom" />

      <param name="base_frame " type="string" value="base_link" />

      <!-- maximum range to integrate -->
      <param name="sensor_model/max_range" value="5.0" />

      <!-- data source to integrate (PointCloud2) -->
      <remap from="cloud_in" to="/zed/zed_node/point_cloud/cloud_registered" />

     </node>    
</launch>

I found this issue #465 , but in my case it didn't help...

After I run RViz, I can only see /zed/zed_node/point_cloud/cloud_registered topic with point cloud, but NOT MarkerArray (/occupied_cells_vis_array), Map (/projected_map), or /octomap_binary.

What am I doing wrong?

Steps to Reproduce

Install ZED SDK and ROS dependencies
Run `roslaunch zed_wrapper zedm.launch' in Terminal 1
Run 'roslaunch octomap_server octomap_zed.launch` in Terminal 2
Open RViz

Expected Result

Expect to see a voxel map

Actual Result

Empty (only point_clouds from original topic)

ZED Camera model

ZED Mini

Environment

Ubuntu 20
ROS Noetic

Anything else?

Thanks a lot in advance!
