Deformation of trajectory when performing alignment about evo

Fixed it! Found error in my data. Now everything works nice.

firstly I would like to start with saying that you've done an outstanding job with this evaluation tool!
I am quite new with the process of evaluation and your tool, so forgive me if I ask something silly. :)

Thank you! There are no silly questions 😄

One thing to add maybe: if you "see that the number of poses for the tested trajectory is now lower", it's probably because the trajectories are matched based on their timestamps before alignment. If there are not enough matches, it can introduces gaps. You can see how many poses are matched when you run it with --verbose / -v logging.

Yes that was exactly the problem. Now we fixed it and its much better! Thank you for responding.
