ground truth
how can i get the ground truth of this datasets? I have the same question, have you solved this?
/odometry topic in the rosbag is the groundtruth trajectory
Thank you for your reply. I have indeed done this before, but I would like to ask why it is like this. Is it because this is created by ARSIM simulation and the /odmetry topic records the ground truth trajectory?
Yes, you are correct. The ground truth pose is from AIRSIM.↳
Can you tell me how to get the groundtruth.txt file ,please? I don’t know how to do.
The ground truth pose is included in the rosbag, not as a text file e.g. groundtruth.txt.

You can transcribe the odmetry content in the bag file to **.txt and extract useful data into TUM format
Why did I translate the odometry topic in the bag into the wrong track，help me

How do I extract track files，please
Sorry for the late reply. Please follow the ROS tutorial to understand how to handle rosbag. You would probably need to install ROS first and do rosbag play ... to play the recorded data. You may also use third party tools such as https://gitlab.com/ternaris/rosbags for instance.
