visualize dynamic map

[hw-zero]

Hi, zhefan. First, thank you for your great work. I encountered a problem when I tried to launch the dynamic_map. According to the README.md, I have tried to launch the esdf_map or dynamic_map. But no dynamic or static obstacles were shown in the RVIZ. I want to know if I should launch other nodes to visualize the results the same in your README?

roslaunch uav_simulator start.launch
# roslaunch map_manager occupancy_map.launch # OK
roslaunch map_manager daynamic_map.launch # no obstacles
roslaunch map_manager rviz.launch
