Hi, If I would like to generate the calib files for each sample like in KITTI,:

would I have to use the functions in DataViewerV2.py to generate these values? Does the camera_to_velodyne returned by the load_calib_data function correspond to Tr_imu_to_velo?

If I am only using the lidar files from lidar_hdl4_last_stereo_left will I be able to iterate over the files and have a corresponding camera calib file and tf tree?

Also, is there a reason some lidar files are .npz and some are .bin?

Thank you for the dataset!

Ah I see that lidar_hdl4_last_stereo_left has the projected files. Which folder contains the pointcloud bin files?

jmiemirza commented 3 years ago

lidar_hdl64_strongest and lidar_hdl64_last contains the .bin files.
