> Yes, it's obtained from LIO-Mapping (using Lidar + IMU). It's mentioned in section V of the paper. @magehrig Hi Mathias, I am also trying to get the camera trajectory...

@magehrig Thanks for your reply. I need a global, drift-free trajctory. I am working on a learning-based visual-LiDAR odometry, but the datasets with longer sequences of synchronized camera and LiDAR...

Yes, take the GPS in would be better, as the groundtruth poses are usually generated from the RTK. But according to the previous comments, it seems that the RTK trajectory...

Thanks a lot, it solves my previous doubts. I had previously thought that the camera trajectory of the training sequences are obtained by directly clipping the trajectory estimated from the...

Never mind, I just meant to say that the estimated rosbag trajectory is in LiDAR coordinate system, so it needs to be transformed to the camera coordinate system by the...

Thanks a lot! For the 20Hz sequence, a possible solution is rescale the topic publish frequence into 10Hz by "rosbag play -r 0.5 lidar_imu.bag". But I'm not too sure how...
