How to integrate INS, GPS and SLAM for Lidar

The instructions to read the data are similar to the ones described in this post, but with accelerations and angular velocities instead of positions / orientations.
This means, we need relative calibration, time synchronization and expected formatting.

Typical data should look like this

Usage is also similar, we need to give it a weight in the SLAM and you may use ‘Optimize Graph with IMU’ for post processing. But we also need to to set the gravity vector ( by default 0,0,-9.80511 ) if the data is containing it.

Hope this helps.
