Main goal has been enabling online adjustment of minimum height for points downprojected as obstacle in order to tweak this value when working in the real world.
Use rosparam get /depth_occupancy_map
to see all available config values or take a look in config/depth_occupancy_map.yaml
.
You may want activate continuous depth mapping with r.toggle_permanent_depth_occupancy_mapping()
while looking to the ground and adjust lower bound for obstacle points with rosparam set /depth_occupancy_map/lower_height_bound <Z THRESHOLD>
. Also check downprojected map while moving because of non-planar 3D movement of robot.
