Thanks for your solid work! https://github.com/pengsongyou/openscene/blob/0f369bc73d0724ae24b5e46bbada193f8ee9d193/scripts/preprocess/preprocess_3d_nuscenes.py#L113

I wanted to understand the preprocessing of nuscenes 3d data, so I called preprocess_3d_nuscenes.py. But I found that the format of the input was inconsistent with the source dataset, and I couldn't find scene.ply. This seems to have gone through some kind of convert. How should I align this part ?

My local original fold tree is as follows.

./
├── bevdepth
├── depth_gt
├── maps
├── samples
├── sweeps
└── v1.0-mini
