Hi, Tanks for your excellent work! But I confuse with the cam_sweeps_info in NuScenesSweepDataset cam_sweeps_info. Where did it get it from？

Hi, Thanks for your interest. This is our defined info with multiple camera sweeps. You can generate it following the step in README like this:

python3 extra_tools/create_data.py nuscenes --root-path ./data/nuscenes --out-dir ./data/nuscenes --extra-tag nuscenes_unified
