Does the ground_truth you show refer to the real location of the vehicle? How did you get it?

The ground truth is collected based on differential GPS, the localization accuracy is around cm level and usually we use it for ground truth. You can refer to KITTI website for more information

Hello, I use kitti_to_bag to convert 2011_09_30_drive_0020 into a bag file. There was a serious drift after playing, I don't know why it happened.

I meet the same problem. Have you solved it?
