Mappping problem

[surajmahangade]

I tried mappping a environment using your model in gazebo.But the map dissappears after moving for some time.
Here is the link to the video
https://drive.google.com/file/d/1Oniq8bKh_OOSfb23sV2u_62Ci7ZQnFue/view?usp=sharing

and my tf_tree

Any idea what might be wrong.

Thank you

Can you post your .launch file? Guess it's RTAB-Map memory parameter.

This is the content of the launch file

Yes, it's RTAB-Map related issue. Try changing Rtabmap/MemoryThr parameter to 0.

[surajmahangade]

I changed the parameter in launch file.
That didn't work.
Still facing the same problem.
Anything else it can be?

Facing the same issue. Tried the possible solutions suggested by you ...no progress

@aayushi363 @surajmahangade Can you provide rosbag files without RTAB-Map and tx2_fcnn_node output, so I can check the issue myself?
