How to use

[mamoru1126]

hello.

I tried to use traversablity_estimation using rosbag file (traversability_estimation/maps/elevation_map.bag),
but I could not. Nothing was displayed in Rviz.

Please teach me how to use traversability_estimation.

The commands I used on the terminal are:

1. roslaunch traversability_estimation traversability_estimation.launch
   ※enable of grid_map_to_initialize_traversability_map is true, grid_map_topic_name is grid_map

2. rosservice call /traversability_estimation/load_elevation_map "~/catkin_ws/src/traversablity_estimation/traversablity_estimation/maps/elevation_map.bag/elevation_map.bag" "grid_map"

3. roslaunch traversability_estimation visualization.launch

I used Rviz after typing 1, 2 and 3 commands.

have you solved the problem?

I am having the same issues and have followed the same steps as mamoru1126.

Does the "grid_map_topic_name" should be the elevation map topic name?

If you are using ANYbotics/elevation_mapping, go to the site to see what services are available.

What you should see is a service that uses the message type of [grid_map_msgs/GetGridMap].
The name of the service is [/elevation_mapping/get_submap].

Then change the service on the following line to "/elevation_mapping/get_submap". Then run roslaunch traversability_estimation traversability_estimation.launch and roslaunch traversability_estimation visualization.launch and you can see from the rviz topic that the node is working fine.
