Elevation Map not Displaying in RViz (elevation_mapping/elevation_map_raw topic not being published)
I have been attempting to use ZED point cloud data to test out the elevation_mapping package.
First, here is the output I get using rqt_graph. The elevation_mapping node is subscribed to the down-sampled point cloud (type sensor_msgs/PointCloud2), the pose of the ZED camera (type geometry_msgs/PoseWithCovariance), and tf.
In RViz, the pointcloud from the ZED camera displays properly, but the elevation mapping data from elevation_mapping_raw is not displaying. Below is a screenshot of my RViz window:
My bagfile info is below. As you can see, the elevation mapping node published 31 /elevation_mapping/elevation_map topic messages. However, it does not seem that any /elevation_mapping/elevation_map_raw topic messages were published.

To add to this - on RViz, I can see that the elevation_mapping/elevation_map topic messages are being published successfully:
However, it appears that the elevation_mapping/elevation_map_raw messages are not being published:
Not sure if this helps, but here is the output from roslaunch elevation_mapping_demos zed_test2.launch (modified version of simple_demo to test elevation mapping with ZED input):

I would be greatly appreciated if you can provide some insight as to why the elevation_mapping/elevation_map_raw is not being published.
Hey, setup should look okay,
I guess there might be problem with the tf/pose information, i.e. the following part from the console:
[ERROR] [1648445958.063837999]: Could not get pose information from robot for time 1648445956.360284. Buffer empty?
[ INFO] [1648445958.736752215]: Waiting for tf transformation to be available. (Message is throttled, 10s.)
@maximilianwulf Is there any way to subscribe to a "fake pose" to see if my pose input is the issue?
Hm, yes, but you have to create the fake pose.
I would actually try the waffle demo first and then just rewire the point clouds, and see if it reacts.
@maximilianwulf Thank you for the advice - I just tried this out.
I'm still getting the same issue where the elevation_mapping/elevation_map topic is being published, but elevation_mapping/elevation_map_raw is not.
Here is what I modified in the turtlesim3_wafffle_demo.launch file. The input to the down-sample filter is now /zed/zed_node/point_cloud/cloud_registered
<!-- Run a passthrough filter to down-sample the sensor point cloud.-->
