IMU preintegration actually not used?

Here, inglobalLocalize.cpp, it seems that imu preintegration odometry for prior to lidar actually cannot be used because the code of lidar incremental pose has been deleted.

I want to ask the same question, it seems that it didnt use the imupreintegration results in code, but I try to use it in the code. Have you tried it?

Yes. Just same as the original version of LIO-SAM but you need to do some tricks to integrate them. I have completed it a few months ago and forgotten what tricks :(
