Hope you have been well. Have always been a fan of rtabmap since the beginning, and have still been experimenting on it as much as I can.
In my gazebo simulation, I noticed some free cells that is often mapped beyond the walls in my simulation, as seen below. Is there a way to modify certain params such that there's no free cells behind the walls (I understand that this isn't realistic in the real world). I am using a 3D lidar for localization and mapping.
This is an example of no free cells beyond obstacles:
