Distortion occurs when comparing with the true trajectory

[HowieHepburn]

Description: My trajctory :(evo_traj tum lio_odom_UrbanTST.tum -p):

GroundTruth:(evo_traj tum gt_slam_UrbanNav-HK-TST-20210517.csv -p):

Comparative:(evo_traj tum --ref gt_slam_UrbanNav-HK-TST-20210517.csv lio_odom_UrbanTST.tum -p):

When I try to use the "-a" command to put two trajectories together for comparison, My trajectory be like this

I'm wondering if this is normal? In addition: evo_ape tum gt_slam_UrbanNav-HK-TST-20210517.csv lio_odom_UrbanTST.tum -ap:

evo_ape tum gt_slam_UrbanNav-HK-TST-20210517.csv lio_odom_UrbanTST.tum -p:

If you add --verbose (or -v), you can see that this probably just caused by not all timestamps being matched to the other trajectory. So not a distortion, just missing data in between.

Thank you very much for your reply, you are right, not all timestamps being matched to the other trajectory, and I have solved the problem by adding t_max_diff=0.1 in my command
