Could you tell me how to create . db file？

Hello, thank you for your outstanding contribution and selfless sharing. I want to develop my own dataset for localization, but I encountered difficulties in the data preprocessing stage. I don't know how to generate. db files in the structFiles folder. I am confused about how to generate three db files for the Nordland dataset. Can you tell me where to learn how to create them? Thank you.

Hi @LLYYQJ ,
You can refer to this for creating/reading dbStruct. If you read through the discussion on that issue and follow the links to other repositories, I think that will answer most of your queries.

Cheers!

Thank you for pointing out the key points. I have reviewed the previous issue, but I am not very careful. I will try to build on this foundation. Thank you again for your valuable work.
