I encountered an error when trying to replicate your code. Could you tell me the reason?

Segmentation fault

Sorry for the delay, I just saw this issue.
I don't see why you'd get a segmentation fault, and I cannot debug this just from this output.

You can try debugging the code using GDB, there are countless tutorials on the internet, to pin-point where in the code the segmentation fault is occurring. If so let me know and I will review it.
To be able to run GDB you'll probably need to add the flag -g in the CMakeLists.txt line 20

Then run the program with GDB should be as easy as: gdb --args ./demo_stereo [... arguments go here] and check where the segfault happens by executing the frame command inside GDB.

Thank you very much for your reply. I found that the problem is that the dbow2 library you provided is different from the one used by orb-slam3, so the orbvoc.txt file cannot be processed. Could you please tell me how to modify the DBow2 library to use ORB-SLAM3
