Unable to load the db file using Rtabmap

kolohe113
Hi, recently I am having issue loading db file in Rtabmap. I am trying to use a Hokuyo LiDAR, a Realsense d435, and wheel encoder from turtlebot to generate a 3D map. This is the warning I got when I open the saved db file using Rtabmap:

"[ERROR] (2018-12-19 16:15:28.156) VWDictionary.cpp:616::addWordRef() Not found word 29617 (dict size=959)

Does this error looks familiar to anyone?

Can you post your launch files?

Even with Rtabmap.launch and setting subscribe_scan to false and the rest unchanged, I am still unable to load the db file

Hi,

The database seems corrupted somehow. You can try to recover the database using rtabmap-recovery tool:
$ rtabmap-recovery my_map.db

cheers,
Mathieu

Do you think this has to do with the Rtabmap's version?

It could, you can see the version doing "$ rtabmap --version" or looking in the About dialog in the interface. It has been a while since I saw this problem, it means the visual word vocabulary was not correctly saved (like rtabmap didn't close properly).

cheers,
