how can i get the ground truth of this datasets?

how can i get the ground truth of this datasets? I have the same question, have you solved this?

kminoda commented 10 months ago

/odometry topic in the rosbag is the groundtruth trajectory

/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?

kminoda commented 10 months ago

Yes, you are correct. The ground truth pose is from AIRSIM.

baohongwei commented 10 months ago

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.

kminoda commented 10 months ago

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

jerryjifjsdbf commented 7 months ago

Is there a truth trace before the VIODE dataset

jerryjifjsdbf commented 7 months ago

The ground truth pose is included in the rosbag, not as a text file e.g. groundtruth.txt.

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.
