Dr RTAB-MAp:
sorry  to bother,i'm newer in slam,i encounter follow issue:
      When I use rtabmap for slam, the map will refresh once at the beginning of slam, but then no matter how I move the unmanned vehicle, the map in rviz2 /map will not change, and the 3d image（points） of rtabmap-rviz will not save the previously recorded image, but only display. I don't understand why this is happening. Can anyone help me? I have been troubled for a long time. Any help is greatly appreciated.
 i use ros2 launch rtab_slam_python rtab_slam.launch.py to start
follow is some prtsc:




rtabmap_rgbd_sync.py
rtab_slam.py
